Limit CPU Usage for a process

Hi,

Using 100% CPU resources may indicate problems in the application under test. I'd recommend discussing this with your developers.

>> How can I limit CPU Usage of a process through TestComplete ?

Do you know if it is possible in Windows? As far as I know, Windows operates with process priorities, but not with CPU usage. So, perhaps, you have to set a lower priority for this process. You can do this through Task Manager, or you can specify the priority when you start a process with the "start" command-line command of the operating system. For information about its arguments, type start /? in the command line.

To set the priority from script test, try using the following code snippet (I found it here http://forum.soft32.com/windows/Limit-CPU-usage-ftopict386586.html):

Const BELOW_NORMAL = 16384 

strComputer = "." 

Set objWMIService = GetObject("winmgmts:" _ 

                    & "{impersonationLevel=impersonate}!\\" _ 

                    & strComputer & "\root\cimv2") 

Set colProcesses = objWMIService.ExecQuery _ 

                   ("Select * from Win32_Process Where Name = 'Notepad.exe'") 

For Each objProcess In colProcesses 

  objProcess.SetPriority(BELOW_NORMAL) 

Next 

For information about the SetPriority function that is used in this code snippet, see the MSDN Library (http://msdn.microsoft.com/en-us/library/aa393587(VS.85).aspx).
