k8s考点灵魂拷问9连击 ReplicaSet 的主要作用是控制副本数量的，这里的每一个副本就是一个 Pod ， ReplicaSet 它是用来确保我们有指定数量的 Pod 副本正在运行的 Kubernetes 控制器，这里为了方便后面统一把 ReplicaSet 简称 RS。 进一步说什么是控制副本数量？ RS确保Pod以你指定的副本数运行，即如果有容器异常退出，会自动创建新的 Pod 来替代，而异常多出来的容器也会自动回收。 假设k8s集群中，你想要运行10个Pod，如果这时候有4个Pod发生故障，异常退出，那么RS会自动创建新的4个Pod来替代发生故障的4个Pod。 RS 尽力保证 系统当前正在运行的 Pod 数 等于期望状态 里指定的 Pod 数目。 你想要10个，那么RS就尽可能保证在任何时候都给你提供10个，没有就创建，多了就删除。 总之，ReplicaSet 尽可能确保任何时间都有指定数量的 Pod 副本在运行。 ReplicationController 控制器（简称为RC）。 在之前旧版本的k8s中，使用的是RC控制器实现了k8s集群的高可用性，它跟现在的RS控制器作用类似，作用是，确保Pod以指定的副本数运行。 ReplicaSet继承了RC的功能，并实现了扩展，主要突出扩展是更强大的 标签选择能力 ，即selector。 进一步说什么是标签选择能力？ ReplicaSet 会通过标签选择器（ Label-Selecto r）管理所有被打上与选择器匹配的标签的容器。 下面通过一段拟人对白，来理解什么是标签选择： RS说：”嘿嘿，我要管理被打上 A，AA，AAA标签的Pod，都不许跑，听我指挥，排队站好，U0001f9cdU0001f3fb立正，向前看！“ Pod-001说：”我被打上了BBB标签，我才不归你管呢！“ Pod-002说：”我被打上了AA标签，快来接管我吧，我准备好了“ Pod-003说：”呜呜，我想独立，我不想被RS管，我要做一个自由自在的孩子，但是不幸的是，我被打上了A标签，RS给我管的紧紧的，我失去了自由，我好可怜呀“ ReplicationController 自己也有标签选择能力，但是它只能选择包含某个标签的匹配Pod； ReplicaSet的选择器在基础上增加了允许匹配缺少某个标签的pod，或包含特定标签名的Pod； 举个例子 两组Pod，env标签分别是 production 和 devel RC 只能匹配其中的Pod-A或者Pod-B中的一个； RS 则可以同时可以匹配并将它们视为一个大组，无论标签env的值具体是什么（env=*）,都可以标签名来进行匹配； 类似其他 Kubernetes API 对象，RS也需要指定 apiVersion 、 kind 、和 metadata 字段。 前面提到了，RS采用了最新的标签选择能力，通过指定 .spec.selector 标签选择器，不仅可根据标签值，甚至连标签名一致都可以进行匹配。 首先如果采用Pod模板创建Pod，会被指定标签， RS会根据标签自动接管Pod 。 再来看看非模板 非模板创建，其实就是直接创建裸的 Pods。 为什么可能会被副本集RS自动接管？ 除非在创建裸Pod的时候，你确保这些裸的 Pods 并不包含可能与你的某个 ReplicaSet 的 .spec.selector 相匹配的标签。 在创建裸Pods前，必须完全排除跟任何RS有可能相同的标签，否则，RS认为你创建的Pod 就是要指定给自己接管的。 首先理解一下问题，循环创建Pod副本？ RS一直在正常工作，维持Pod副本数量，缺少就创建，多了就删除。问题来了，一直创建，然后又删除，却不能稳定Pod副本数量？ 看下这个 循环过程 总之，RS检测副本数量，不是比10个多，就是比10少， 一直难以维持10个有效副本 。 既然排除了是Pod内部故障问题，那么从RS角度进行可能分析，可以初步判定是多个RS标签选择器规则重复导致的。 分析初步判定原因 ReplicaSet 会通过标签选择器（Label-Selector）管理所有带有与选择器匹配的标签的容器。 创建 Pod 时，它会认为所有 Pod 是一样的，是无状态的，所以在创建顺序上不会有先后之分。 使用相同的标签选择器创建多个 ReplicaSet ，则多个RS无法识别哪个Pod是自己创建的，都会认为是归属于自己管理的Pod。 例如 双方的当前状态始终 不等于期望状态，这就会引发问题 ，因此确保 ReplicaSet 标签选择器的唯一性这一点很重要。 本期暂时讨论上述5点，下期完成下面4点 推荐阅读： 【探针配置失误，线上容器应用异常死锁后，kubernetes集群未及时响应自愈重启容器？】 推荐休闲阅读： 【囧么肥事】

歌曲名:Ghetto Gospel Remix (Feat Tupa歌手:Akon专辑:In My Ghetto Vol 2-Umvd Labels Uh, hit them with a little ghetto gospel.Those who wish to follow me. (my Ghetto gospel)I welcome with my hands.And the red sun sinks to last into the hills of gold. And peace to this young warrior,Without the sound of guns.If I could recollect before my hood days. I sit and reminisce, thinking and bliss on the good days.I stop and stare at the younger, my heart goes to m.They tested, it was stressed that they under.And nowadays, things changed. Everyone ashamed to the youth, cuz the truth looks strange.And for me it reversed, we left them a world that cursed, and it hurts.Cause any day theyl push the button.And all commend, like Malcom X and Bobby Hunton, died for nothin?Don make me get teary, the world looks dreary.When you wipe your eyes, seeing clearly.There no need for you to fear me. If you take your time to hear me,maybe you can learn to cheer me. It ain about black or white, cuz wee human. I hope we see the light before it ruined.My ghetto gospel. Those who wish to follow me. (Ghetto gospel)I welcome with my hands. And the red sun sinks to last into the hills of gold.And peace to this young warrior,Without the sound of guns. Tell me do you see that old lady, ain it sad.Living out of bags, plus she glad for the little things she has.And over there there a lady, crack got her crazy. Guess she giving birth to a baby. I don trip and let m fade me,? wee droppin?to another form of slavery. Even now I keep discouraged. Wonder if they take it all back,Will I still keep the courage? I refuse to be a role model.I set goals, take control, drink out my own bottles.I made mistakes, but learned from every one.And when it said and done. I bet this brother be a better one. If I upset, you don stress. Never forget that God hasn finished with me yet. I feel his hand on my brain. When I write rhymes,I go blind, and let the lord do his thing. But am I less holy?Cuz I choose to puff a blunt and drink a beer with my homeyz.Before we find world peace. We gotta find peace in the war on the streets. My ghetto gospel.Those who wish to follow me. (Ghetto gospel) I welcome with my hands.And the red sun sinks at last into the hills of gold. And peace to this young warrior, Without the sound of guns. Lord can you hear me speak.http://music.baidu.com/song/1639684

A friend who is a police in Guangzhou got married yesterday.He once helped me get out of a very sticky situation without asking for any demand. I am sorry that I couldn"t give my congratuation to him in person on his big day. Two years ago, a stuffy summer evening I was robbed when walking on the street with my another female friend after we left a hair salon. Two guys riding on a motorcycle behind us rushed onto the sidewalk and pulled my purse away. I fell down on the hard concrete ground and the mortorcycle was hitting by a electricity pole.They quickly shifted the direction and zipped away. We were so appalled and black-out that we fot to dial 110.I called my friend, the police, for help with tears in my eyes. Ten minutes later, he showed up and send me to a hospital nearby. The young resident took little care of my spot where I got hurt. Misfortunes never e alone.Three days later, it became so inflaming and swollen because of the heat of summer that I couldn"t walk. I vented my anger and anxiety everywhere I could and decided to change another better hospital.In order to avoid making further and worse problem then and future, I decided to let a specific doctor to diagose it. It was a bolt out of the blue to learn that I needed a surgery, whereas it was incredible to undertake a surgery without any local or gerenal anesthesia. I extremely suffered from it. It was him who held my hand tightly without any hesitation during the whole process and it was him who took me back and forth to hospital to do the daily checks. There were no sufficient words expressing my thanks for him.It took me a month back to the normal track until the Mid-Autumn day.My friend availed himself of the benefit from his job to offset the 70% of the total costs. However, what the quite unhappy thing was a hard-to-miss and hard-to-fade mark on my right leg. I need another surgery to remove it.It seemed to be a mark of friendship for me. The old saying goes: Fortune makes friends and adversity tests them. I"m lucky and proud to have such a genuine friend. The bad luck happening to me is unfettable, the friend,however, is more unfettable.

retained earnings(beginning)+net income-dividends=retaine earning(end of period)书上标准答案

表语是at the weekend后面的among rich families是介词结构，做状语。状语和定语去区别，就是定语是修饰名词的，而状语时修饰谓语动词的。或者说，状语不是修饰名词的。

前者是动名词，保留了动词的特点，后面要跟自己的宾语（因为retain是及物动词），如：Theythistimeembracedheartily,andwithoutretaininganymalice.他们这次热情而毫无恶意地拥抱了彼此。后者是名词，不能跟名词，但可说：theretentionofsth.

u2022 copy: 用于希望保持一份传入值的拷贝，而不是值自身的情况，即把原来的对象完整的赋值到另外一地方，重新加载一内存区，一个地方变了不影响另一个地方的对象。u2022 assign: 简单的直接赋值，相当于说两个对象指向同个内存区，一个地方的变了，其他的也跟着改变。u2022 retain:释放旧的对象,将旧对象的值赋予输入对象,再提高输入对象的索引计数 为1那上面的是什么意思呢?Copy 其实是建立了一个相同的对象,而 retain 不是:比如一个 NSString 对象,地址为 0×1111,内容为@”ABC”Copy 到另外一个 NSString 之 后,地址为 0×2222,内容相同,新的对象 retain 为 1, 旧 有对象没有变化retain 到另外一个 NSString 之 后,地址相同(建立一个指针,指针拷贝),内容当然相 同,这个对象的 retain 值+1assign 地址还是0x1111,内容也还是“ABC”。也就是说,retain 是指针拷贝,copy 是内容拷贝。strong，weak 用来修饰属性。strong 用来修饰强引用的属性；@property (strong) SomeClass * aObject; 对应原来的 @property (retain) SomeClass * aObject; 和 @property (copy) SomeClass * aObject; weak 用来修饰弱引用的属性；@property (weak) SomeClass * aObject; 对应原来的 @property (assign) SomeClass * aObject;

累加语句new_income+income;相当于下面的程序段：retainnew_income0;new_income=sum(new_income,income);所以说，上面的两个程序都使用了retain的功能，结果当然一样！想体现出retain的作用，可以试试把累加语句new_income+income;改为new_income=sum(new_income,income);

1、trash属于英语,准确的说是美国英语里的外来语,并非根红苗正的英文单词,通常用其动词形式,和mess up意思差不多，garbage比较常用,rubbish的使用频率稍低 。例句：1. In her home, garbage was fed to the pigs.在她家,剩菜用来喂猪.2.Our job is to clear away the rubbish.我们的工作是清除这些垃圾.2、retain有存留之意，比如保持安静,保持温暖之类,keep quiet,stay quiet,keep warm stay warm都可以 在表示 被动的行为,即一个事物保持另一个事物的状态,只能用keep 。例句：1、He remained in his seat after all the other students had gone home.2、She knew she must keep calm.I wish those children would keep quiet.3、refuse to do sth 拒绝做某事。resist doing sth 抵制做某事。例句：1、a reject from the varsity team; a tire that is a reject. 被大学代表队拒绝的人；被拒绝使用的轮胎 。2、She was refused admittance. He refused treatment. 她被拒绝加入；他拒绝治疗 。

　　copy与retain的区别：　　copy是创建一个新对象，retain是创建一个指针，引用对象计数加1。Copy属性表示两个对象内容相同，新的对象retain为1 ，与旧有对象的引用计数无关，旧有对象没有变化。copy减少对象对上下文的依赖。　　retain属性表示两个对象地址相同（建立一个指针，指针拷贝），内容当然相同，这个对象的retain值+1也就是说，retain 是指针拷贝，copy 是内容拷贝。　　　　当然在ios中并不是所有的对象都支持copy，mutableCopy，遵守NSCopying 协议的类可以发送copy消息，遵守NSMutableCopying 协议的类才可以发送mutableCopy消息。假如发送了一个没有遵守上诉两协议而发送 copy或者 mutableCopy,那么就会发生异常。但是默认的ios类并没有遵守这两个协议。如果想自定义一下copy 那么就必须遵守NSCopying,并且实现 copyWithZone: 方法，如果想自定义一下mutableCopy 那么就必须遵守NSMutableCopying,并且实现 mutableCopyWithZone: 方法。　　首先我们需要有这样的一个前提：　　［array addObject:obj];　　这样obj的引用计数会增加1，如果使用remove则obj的引用计数会减一。　　ios对集合的内存处理就是这样的。　　那么，假设obj只被array拥有：　　id temp ＝ [array objectAtIndex:0];　　[array removeObjectAtIndex:0];　　如果你再要使用temp就会出错，因为这个时候obj已经被释放了。　　（提醒一下，如果用NSString做测试，要注意@“abc”是常量 :-) ）　　由于在程序中经常会遇到集合类的传值，所以，简单的retain未必够用，需要对集合内容的拷贝，也就是深拷贝。　　下面我们就来探讨一下。　　Ios提供了copy和mutablecopy方法，顾名思义，copy就是复制了一个imutable的对象，而mutablecopy就是复制了一个mutable的对象。以下将举几个例子来说明。　　1. 系统的非容器类对象　　这里指的是NSString,NSNumber等等一类的对象。　　NSString *string = @"origion";　　NSString *stringCopy = [string copy];　　NSMutableString *stringMCopy = [string mutableCopy];　　[stringMCopy appendString:@"!!"];　　查看内存可以发现，string和stringCopy指向的是同一块内存区域(又叫apple弱引用weak reference)，此时stringCopy的引用计数和string的一样都为2。而stringMCopy则是我们所说的真正意义上的复制，系统为其分配了新内存，但指针所指向的字符串还是和string所指的一样。　　再看下面的例子：　　NSMutableString *string = [NSMutableString stringWithString: @"origion"];　　NSString *stringCopy = [string copy];　　NSMutableString *mStringCopy = [string copy];　　NSMutableString *stringMCopy = [string mutableCopy];　　[mStringCopy appendString:@"mm"];//error　　[string appendString:@" origion!"];　　[stringMCopy appendString:@"!!"];　　以上四个NSString对象所分配的内存都是不一样的。但是对于mStringCopy其实是个imutable对象，所以上述会报错。　　对于系统的非容器类对象，我们可以认为，如果对一不可变对象复制，copy是指针复制（浅拷贝）和mutableCopy就是对象复制（深拷贝）。如果是对可变对象复制，都是深拷贝，但是copy返回的对象是不可变的。　　2. 系统的容器类对象　　指NSArray，NSDictionary等。对于容器类本身，上面讨论的结论也是适用的，需要探讨的是复制后容器内对象的变化。　　//copy返回不可变对象，mutablecopy返回可变对象　　NSArray *array1 = [NSArray arrayWithObjects:@"a",@"b",@"c",nil];　　NSArray *arrayCopy1 = [array1 copy];　　//arrayCopy1是和array同一个NSArray对象（指向相同的对象），包括array里面的元素也是指向相同的指针　　NSLog(@"array1 retain count: %d",[array1 retainCount]);　　NSLog(@"array1 retain count: %d",[arrayCopy1 retainCount]);　　NSMutableArray *mArrayCopy1 = [array1 mutableCopy];　　//mArrayCopy1是array1的可变副本，指向的对象和array1不同，但是其中的元素和array1中的元素指向的是同一个对象。mArrayCopy1还可以修改自己的对象　　[mArrayCopy1 addObject:@"de"];　　[mArrayCopy1 removeObjectAtIndex:0];　　array1和arrayCopy1是指针复制，而mArrayCopy1是对象复制，mArrayCopy1还可以改变期内的元素：删除或添加。但是注意的是，容器内的元素内容都是指针复制。　　下面用另一个例子来测试一下。　　NSArray *mArray1 = [NSArray arrayWithObjects:[NSMutableString stringWithString:@"a"],@"b",@"c",nil];　　NSArray *mArrayCopy2 = [mArray1 copy];　　NSLog(@"mArray1 retain count: %d",[mArray1 retainCount]);　　NSMutableArray *mArrayMCopy1 = [mArray1 mutableCopy];　　NSLog(@"mArray1 retain count: %d",[mArray1 retainCount]);　　//mArrayCopy2,mArrayMCopy1和mArray1指向的都是不一样的对象，但是其中的元素都是一样的对象——同一个指针　　//一下做测试　　NSMutableString *testString = [mArray1 objectAtIndex:0];　　//testString = @"1a1";//这样会改变testString的指针，其实是将@“1a1”临时对象赋给了testString　　[testString appendString:@" tail"];//这样以上三个数组的首元素都被改变了　　由此可见，对于容器而言，其元素对象始终是指针复制。如果需要元素对象也是对象复制，就需要实现深拷贝。http://developer.apple.com/library/mac/#documentation/Cocoa/Conceptual/Collections/Articles/Copying.html　　NSArray *array = [NSArray arrayWithObjects:[NSMutableString stringWithString:@"first"],[NSStringstringWithString:@"b"],@"c",nil];　　NSArray *deepCopyArray=[[NSArray alloc] initWithArray: array copyItems: YES];　　NSArray* trueDeepCopyArray = [NSKeyedUnarchiver unarchiveObjectWithData:　　[NSKeyedArchiver archivedDataWithRootObject: array]];　　trueDeepCopyArray是完全意义上的深拷贝，而deepCopyArray则不是，对于deepCopyArray内的不可变元素其还是指针复制。或者我们自己实现深拷贝的方法。因为如果容器的某一元素是不可变的，那你复制完后该对象仍旧是不能改变的，因此只需要指针复制即可。除非你对容器内的元素重新赋值，否则指针复制即已足够。举个例子，[[array objectAtIndex:0]appendstring:@”sd”]后其他的容器内对象并不会受影响。[[array objectAtIndex:1]和[[deepCopyArray objectAtIndex:0]尽管是指向同一块内存，但是我们没有办法对其进行修改——因为它是不可改变的。所以指针复制已经足够。所以这并不是完全意义上的深拷贝，但是apple的官方文档将其列为deep copy了，并添加了copy和mutablity的关系说明，故在此做一说明

preserve更多的是有预留的意思,比如说在国外停车场看到写着preserved标志,你就不能在这停车了,这些是预留车位. preserve表示保留时,意思和retain差不多,就看习惯用法了. Few of her early articles are preserved.她早期的文章没有几篇留存下来. retain是保留意见,保留权利的意思.比如说： We shall retain our rights.我们将保留我们的权利. 其他的保留用得最多的是keep,这个词就不用多说了吧. 还有就是：hold保持住；reserve也有预留的意思,如餐馆预定；save保存；withhold保留

retain和strong，assign和weak的区别这两组词在意思上根本不存在相同或相近意义，也就是说它们在意义上风马牛不相及。如果说找反义词，那么strong和weak可以算一对反义词。而retain, assign就没有什么关联的地方了。1. retain: verb, to continue to have that thing(动词)保留；保持；保存He retains a deep respect for the profession.他对这个职业仍然深怀敬意The interior of the shop still retains a nineteenth-century atmosphere.这家商店的内部装修仍然保留着19世纪的风格。Other countries retained their traditional and habitual ways of doing things.其他国家仍然保持着他们做事的传统和习惯。If left covered in a warm place, this rice will retain its heat for a good hour.如果加盖放在暖和的地方，这些米饭可以保温足足一个小时。2. strong: adjective, (someone/an animal is) healthy with good muscles and can move or carry heavy things, or do hard physical work(形容词)强壮的；健壮的；力气大的I"m not strong enough to carry him.我力气不够大，抱不动他。I feared I wouldn"t be able to control such a strong horse.我怕我驾驭不了这么强壮的马。3. assign: verb, give a piece of work to someone(动词)分派工作；布置作业Later in the year, she"ll assign them research papers.今年晚些时候，她将给他们指定研究论文。When I taught, I would assign a topic to children which they would write about.我教课时会给孩子们布置一个题目，让他们就这个题目写点东西。When teachers assign homework, students usually feel an obligation to do it.当老师布置家庭作业的时候，学生们通常觉得做作业是分内之事。4. weak: adjective, someone is not healthy or does not have good muscles, so that they cannot move quickly or carry heavy things(身体)虚弱的，无力的His arms and legs were weak.他的四肢虚弱无力。I was too weak to move or think or speak.我太虚弱了，无法动弹，无法思考，也无法说话。

很大区别：retain：保持strong：强如果是retain strong: 保持那么强

对变量进行值的初始化和保留到下一个迭代步的作用。举例：有个数据集有10条记录。retain a;a=sum(a,1);则10条记录的a变量的值是1,2,3,4,5,6,7,8,9,10.如果不retain a;则都是1.在你使用INPUT语句的时候结合RETIAN可以认为是对新增变量的一个值初始化，当然你要赋予一个初始值。如果没用retain，结果就是只有第一行有值。不知道这么说是否帮到你。

retain有存留之意例如We retained the original fireplace when we decorated the room.我们装修房间时保留了原来的壁炉 (存留之意-原本有的东西保留下来)在表示 主动的行为，即对象是有意识的保持 比如保持安静，保持温暖之类，keep quiet, stay quiet, keep warm stay warm都可以 在表示 被动的行为，即一个事物保持另一个事物的状态，只能用keep 比如： keep me warm, keep me alive 等等 希望采纳

retain 保留，留住，拦住（及物动词） preserve 保存，维护，维持，禁猎（及物，注重保护，不让其灭绝或遭到破坏）

retaining 是动名词 可做形容词用；retaintion是名词

remain doing1.retain 存留之意We retained the original fireplace when we decorated the room.我们装修房间时保留了原来的壁炉 (存留之意-原本有的东西保留下来)2.remain 是保持 原来状态 (关键在"状态" )remain standing, seated 一直站着,坐着试想想看,如果用retain 的话,完全就马屁不通了

它都提示让你运行CHKDSK了，那你就运行吧。^_^在开始-运行中输入“CHKDSK C：/F”如果你的系统是在别的盘，就把“C：”换成你系统所在的盘符名，如“D：”然后系统可能会提示你“什么无法锁定当前驱动器，……是否计划在下次系统重新启动时检查这个卷？”按一下“Y”就可以了。重启计算机。应该就OK了，如果还不行那就重装系统吧。对了，如果根本进不了系统，那也可以在“安全模式”下用这个命名。在开机的时候按住“F8”会出现系统启动菜单，可以从中选择以安全模式启动。

AMD公司提出的3DNow!指令集应该说出现在SSE指令集之前，并被AMD广泛应用于其K6-2 、K6-3以及Althon（K7）处理器上。3DNow!指令集技术其实就是21条机器码的扩展指令集。与Intel公司的MMX技术侧重于整数运算有所不同，3DNow!指令集主要针对三维建模、坐标变换 和效果渲染等三维应用场合，在软件的配合下，可以大幅度提高3D处理性能。后来在Althon上开发了Enhanced 3DNow!。这些AMD标准的SIMD指令和Intel的SSE具有相同效能。因为受到Intel在商业上以及Pentium III成功的影响，软件在支持SSE上比起3DNow!更为普遍。Enhanced 3DNow!AMD公司继续增加至52个指令，包含了一些SSE码，因而在针对SSE做最佳化的软件中能获得更好的效能。PCI PREFETCH 是基于PCI总线的一种优化性能的功能，通过对数据的预读取来达到快速响应的效果，好像现在AMD主板都没有这个功能了

微软在Windows Vista中推出了一项新技术--Superfetch。据微软官方宣称，该技术采用了新算法，可以高效提高硬盘工作效率。它不但继承了Windows XP预取技术的全部优点，还进一步具备监视程序运行时状况，时间等详细情况的功能，可以根据用户的使用习惯，自动预先将存放在硬盘的交换文件转换到内存页面中去，使用户经常运行的程序启动时的速度得到进一步的加快.禁用Superfetch具体方法如下:1.进入控制面板，双击“管理工具”(在“经典视图”模式下)，在打开的对话框中的右侧区域内，找到并双击“服务”。2.随后系统会再次弹一窗口，请在列表中找到并双击“Superfetch”，在弹出的对话框中将其禁用3.由于我们不能确定Windows Vista系统的“Superfetch”技术是利大于弊，还是弊大于利，所以建议大家还是先以“稳妥”为重。至少，禁用“Superfetch”并不会对系统有损害，顶多就是系统“也许会慢一点

1.在Petfetch找到就是（或类似）“SVCHOST.EXE-3530F672.pf”的就对，不然就有问题。2.可以说，只要有一个svchost.exe不是以SYSTEM、Local Service和Network Service（不分大小写）的用户启动，就有问题。而可运行的svchost.exe只在system32中有。3.打开一个特别普通的文件夹都特别慢？Windows的通病。希望你习惯。 4.所有的svchost.exe都是小写。你的全是小写，应该没问题。建议先切换到安全模式，然后再用杀毒软件（最新升级）全盘扫描。

Windows XP是允许我们设置预读的对象。 方法就是：打开注册表编辑器，依次展开HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlSession ManagerMemory ManagementPrefetchParameters分支，在右侧窗口中双击"EnablePrefetcher"，在打开的"DWORD"值编辑窗口中，可以对Windows XP进行预读设置： 将该值设置为"0"，即为取消预读功能； 设置为"1"，系统将只预读应用程序； 设置为"2"，系统将只预读Windows系统文件； 设置为"3"，系统将预读Windows系统文件和应用程序。

可以选择使用除IE外其他浏览器，像遨游、火狐、360等，软件自带自动清除记录功能，设置一下就可以了，其中360安全浏览器有个无痕浏览功能，不产生临时文件。自己选择合适的浏览器下载。

windows安装的目录比如系统安装在c:windows那么%windir%就代表c:windowsPrefetch文件夹是WindowsXP自动创建的，主要用于加快系统启动的速度。正常运行的情况下，WindowsXP会自动记录下启动时运行的每一个程序，并建立一个资料索引以加快下一次启动的时间。而当运行的程序重名时，系统会自动在程序名的后面添加一个“后缀”，随着使用时间的变长，Prefetch文件夹内会堆放许多垃圾，反而会拖慢系统，所以如果你有精力的话，还是建议对其进行定期删除。del/f/s/q%windir%prefetch*.*就是删除prefetch文件夹下的垃圾

不可以！我知道你想要清理windows的预读文件*.pf而*.pf保存在文件夹prefetch中，不过prefetch里面还有其它文件，但是注意在清理*.pf时，应该保留其他文件，如：ini文件,因为它们记录着你机器中程序运行的信息，有时候诊断故障时需要。你可以使用搜索功能——*.pf...

保存时候选择所有文件，然后手动写.bat就可以了另外建议你在注册表里面把prefetch的参数修改为2就可以了

可删除可不删除。这是系统预读文件夹是否C:WINDOWSPrefetch下的吧。。这文件夹只是加快系统速度的。。给你个设置方案在使用WindowsXP较长时间后，我们会发现系统运行速度明显慢了下来，用多优化软件、卸载已经安装的软件都解决不了问题。究竟为什么呢？原来罪魁祸首就是预读设置。在“Windows＼Prefetch”文件夹面有很多个以PF为扩展名的文件，这就是预读文件，如果将里面的文件清空以后，你就会发现系统运行速度又恢复正常了！看来，预读设置可以提高系统速度，但是使用一段时间后，预读文件夹里的文件又会变得很多了，导致系统搜索花费的时间变得很长。而且有些应用程序会产生死链接文件，进而加重了系统搜索的负担。因此，我们应该定期删除这些预读文件，用以提高开机速度。当然，WindowsXP重新设置预读对象是允许的。具体方法是：打开注册表编辑器，依次展开HKEY_LOCAL_MACHINE＼SYSTEM＼CurrentControlSet＼Control＼SessionManager＼MemoryManagement＼PrefetchParameters分支，在右侧窗口中双击“EnablePrefetcher”，在打开的“DWORD”值编辑窗口中，可以对WindowsXP进行预读设置：将该值设置为“0”，即为取消预读功能；设置为“1”，系统将只预读应用程序；设置为“2”，系统将只预读Windows系统文件；设置为“3”，系统将预读Windows系统文件和应用程序。一般我们将该值设置为“2”即可，当然，如果你的计算机配置很高，如使用PIII800MHzCPU以上的建议将数值数据更改为4或5，也可以保留数值数据为默认值即3。这样可以加快系统运行速度。

分类: 电脑/网络 >> 反病毒 问题描述: 我的SVCHOST.EXE在进程中的CPU使用率达到了90%以上 解析: Svchost.exe是NT核心系统的非常重要的进程，在进程中是不定数的，要看工作状态。 system,local service和neork service的Svchost.exe是正常的进程。 Svchost.exe文件存在于“%systemroot% system32”目录下，它属于系统的共享进程。随着windows系统服务不断增多，为了节省系统资源，微软把很多服务做成共享方式，交由 svchost.exe进程来启动。但svchost进程只作为服务宿主，并不能实现任何服务功能，即它只能提供条件让其他服务在这里被启动，而它自己却不能给用户提供任何服务。这些系统服务是以动态链接库（dll）形式实现的，它们把可执行程序指向 svchost，由svchost调用相应服务的动态链接库来启动服务。 现在也在有部分木马病毒利用Svchost.exe启动到进程执行，以达到不可告人的目的。 Generic Host Process for Win32 Services动态连接库主机处理服务通过Svchost.exe来完成，文件对那些从动态连接库(DLL)中运行的服务来说是一个普通的主机进程名。Svhost.exe文件定位在系统的Windowssystem32文件夹下。在启动的时候，Svchost.exe检查注册表中的位置来构建需要加载的服务列表。这就会使多个Svchost.exe在同一时间运行。 由于svchost.exe处于Windowssystem32才是标准的，如果svchost.exe在其他目录下，这是不明的文件。全盘搜索svchost.exe，以如果不是在这个目录的，全部直接删除。（注：除系统恢复文件包driver.cab内的除外）。 检查某些网络上的木马是否通过Downloader下载到临时文件夹后产生变身文件，然后通过借助svchost.exe连接网络。打开我的电脑，从工具->文件夹选项，在查看中，勾选[显示系统文件夹的内容]，去掉勾选 [隐藏受保护的操作系统文件]的勾。选择[显示所有文件]，去掉隐藏已知的后缀名。 然后到以上描棕的文件夹里，把相应的病毒文件删除。 请正确判断文件是否系统文件还是伪系统文件，把它们一一删除。 在资源管理器的地址栏上直接输入： C:Documents and Settings当前用户名Local SettingsTemporary Inter FilesContent.IE5 C:Documents and Settings当前用户名Local SettingsTemporary Inter Files C:Documents and Settings当前用户名Local SettingsTemp 这三个临时文件夹中的文件全部直接删除。 还需注意的是，有些病毒把SVCHOST.exe的字母通过大写方式混淆，字母O其实是数字0，亦要把字母O改为数字0搜索。同时注意一下进程还有没有混淆的文件执行，例如：svohost.exe、syohost.exe、，或是后缀名不同，例如：svchost、svchost.scr。

windows vista 和win7 需要关闭这两者 以免影响性能 xp以前只有prefetch而 windows8 以上的系统 已经改进了其对于ssd的影响 所以不需要再关闭

PCI接口芯片如（9030）在设置prefetch后，可以通过内部FIFO预取局部总线上的数据（顺序地址），PCI总线从FIFO上取数，而不是从局部总线上取。

是不是右下角提示xxx损坏文件，文件或目录C:WindowsPrefetchxxx.pf已损坏且无法读取，请运行chkdsk工具。点击开始----运行----输入chkdskC:/f/r然后点“确定”。它会问你“是否强制卸下该卷”，你选择“Y”。然后系统开始扫描磁盘上的文件系统错误（注意命令中的空格）。或者直接找到并删除C:WindowsPrefetch内的所有文件。

用命令行可以简化复杂的鼠标操作，实现后台自动化下载。Prefetch是Windows系统预读文件“缓存”机制所使用的文件夹，让过去打开过的程序、服务再次打开时更快捷。它包含了应用程序加载的文件的信息。在预取文件中的信息用于优化下次运行这些应用程序的载入时间。通过对用户习惯进行分析，能够在预定时间内将可能执行的代码提前调入，从而提高整体响应速度。看起来似乎大幅的占用了物理内存，原因不是说真的耗费资源，而是为了合理的利用全部的物理内存。

最好不要删

C:WINDOWSPrefetch 是系统预读文件夹，不是病毒 Windows之所以自动创建Prefetch文件夹，是为了加快系统启动的进程。Windows将会自动记录下启动时运行的每一个程序，并根据这份资料来加快下一次启动的时间。电脑中的程序成千上万，即使出现重名的程序也不足为奇，碰到这种情况，系统将会自动在程序名的后面添加一个“后缀”，这也就是为什么有些文件名的后面会出现一连串的数字、字母和.pf的扩展名的原因.时间久了，Prefetch文件夹内自然会堆放了许多垃圾，特别是如果用户经常更换电脑配置的话，系统以前记录的进程资料就没有任何用处了。你完全可以放心大胆地将Prefetch文件夹清空，不用害怕，即使删除的文件中有有用的资料，Windows也会自动地重新创建.
