Limiting 7zip CPU usage on Windows Server 2008 (from batch file)

  • 772

Does anyone know of a way (specific to 7zip or general) to limit the CPU usage of 7zip while it is archiving a long list of files? OS is Windows Server 2008 R2, and 7zip is run via command line from a batch file.

  1. Don't worry about the actual CPU percentage, instead you should start the process using a different priority. So from the command line you should be able to use start /low command to start a command that only runs the system is IDLE.

  2. If you are working in powershell you can do something like this: 

    $start = New-Object System.Diagnostics.ProcessStartInfo
$start.Arguments = "--argument1 --argument2"
$start.FileName = "C:\bin\7zip.exe"
$proc = New-Object System.Diagnostics.Process
$proc.PriorityClass = [System.Diagnostics.ProcessPriorityClass]::BelowNormal
$proc.StartInfo = $start
$proc.Start().WaitForExit()

  3. I am using Process Explorer on all servers. When I just want to limit a one time execution of a process, I can choose the priority through the context menu of the process 7z.exe - see attached image. Set priority to Idle in context menu
