Powershell limits the CPU similarity of processes (set affinity)

The CPU usage of the site has been monitored in the last two days. If you want to restrict the site to a maximum of three cores on a 4-core server, you can set the maximum CPU usage of the site to 75%;

(1) Use scheduled tasks to regularly execute the following powershell scripts;

<# Script's function: Set affinity of w3wp.exe to cpu1, cpu2, cpu3 Script Editor: snil Date: 2014-08-08 refer to website: http://technet.microsoft.com/zh-cn/subscriptions/index/system.diagnostics.process.processoraffinity http://waynes-world-it.blogspot.com/2009/06/processor-affinity-on-windows-server.html #> $ w3wps = Get-process-processname "w3wp" foreach ($ w3wp in $ w3wps) {$ w3wp. processoraffinity = 0x0e}
 

For an explanation of "0x0e", refer to: http://technet.microsoft.com/zh-cn/subscriptions/index/system.diagnostics.process.processoraffinity

 

(2) manual operation designation; (this method is time-sensitive and requires manual operation once a day, which is temporary ;)

1. Open the resource manager and find the site to be qualified. Right-click and select "set affinity ..."

650) This. width = 650; "style =" border-bottom: 0px; border-left: 0px; border-top: 0px; border-Right: 0px; "Title =" image "border =" 0 "alt =" image "src =" http://img1.51cto.com/attachment/201408/8/907015_1407467656UFTo.png "Height =" 149 "/>

2. Check the specified CPU and click OK;

650) This. width = 650; "style =" border-bottom: 0px; border-left: 0px; border-top: 0px; border-Right: 0px; "Title =" image "border =" 0 "alt =" image "src =" http://img1.51cto.com/attachment/201408/8/907015_1407467657aRCk.png "Height =" 244 "/>

 

(3) Use wsrm limitation. (This function is not recommended. The wsrm function has been canceled after server 2012 and is replaced by some hyper-V functions)
