  1. I took a script written by Beege, optimized the code, and removed the global variables. Its one function, reliable, and very easy to use or modify to your needs. I decided to post it because I found it very hard to find a reliable way to get the cpu percentage of a given process. I know that there are a few different methods but I deem WMI unreliable and everything I tried before optimizing this function was to slow i.e. freezing when other CPU intensive processes were active. When monitoring a potentially CPU intensive process, I found it necessary to increase the script's priority otherwise the script/system would freeze which is exactly what I was attempting to prevent! See Beege's updated post: #NoTrayIcon #include <WinAPI.au3> HotKeySet('{ESC}', '_Exit') Func _Exit() Exit EndFunc ;==>_Exit _LimitProcessCPU("MediaServer.exe", 10, 1, 5) Func _LimitProcessCPU($vProcess, $nLimit, $nInterval = 1, $nScriptPriority = 2) Local $nProcessCpu = -1, $nOverLimit = 0 While ProcessExists($vProcess) $nProcessCpu = _ProcessCPU($vProcess, $nScriptPriority) If $nProcessCpu > 50 Then $nOverLimit += 1 Else $nOverLimit = 0 EndIf If $nOverLimit > $nLimit Then $nOverLimit = 0 ProcessClose($vProcess) ; < - Replace this with what you need.

  2. CPU Multi-Processor Usage This is an example of getting and displaying processor usage for all processors in a system. It uses the 'undocumented' NtQuerySystemInformation function to gather processor usage information and then does calculations based on the delta of two readings. I wrote this as an alternative to using my >Performance Counters UDF - specifically, check out >Example # 4: System CPU Usage (by Processor). There is now a new interface, as well as two ways to track CPU usage. The first method tracks usage for all CPU's, and additionally produces an overall CPU usage result. The second method tracks Overall CPU usage - a combined value representing all cores as one unit. Note that this second method uses GetSystemTimes, which requires Windows XP SP1 or higher. The usage works like this for all CPU's: $aCPUsUsageTracker = _CPUsUsageTracker_Create() $iTotalCPUs = $aCPUsUsageTracker[0][0] ; Call the following repeatedly - $aCPUsUsageTracker will be updated automatically: $aPercents = _CPUsUsageTracker_GetUsage($aCPUsUsageTracker) For Overall CPU usage, either look at $aPercents[$iTotalCPUs] above, or use this interface (reliant on GetSystemTimes): $aCPUOverallTracker = _CPUOverallUsageTracker_Create() ; Call the following repeatedly - $aCPUOverallTracker will be updated automatically: $fUsage = _CPUOverallUsageTracker_GetUsage($aCPUOverallTracker) _ Need to see how CPU usage is affected? A simple tool I use to stress-test individual CPU cores is Stress Prime 2004, which can be run multiple times. P.S. All I ask is that you acknowledge me in some way if you use any of this code. updates: 2013-08-31: - Added a simple Overall and Idle CPU usage example 2013-06-18: - Changed interface for getting CPU usage.
