Balance CPU Utilization

Reduce the priority (limit the CPU usage) of background processes that eat a lot of CPU, temporary, until CPU usage returns to a reasonable level -Turn this feature On or Off

Total system wide CPU usage when start to limit CPU usage of processes - When CPU usage becomes greater than specified value, AnVir Task Manager reduces the priority of all processes that run in background and use a lot of CPU.

Maximum allowed CPU usage per a process before reduce its priority - If a process uses less CPU than specified value, its priority will not be reduced.

CPU usage of a process before increase its priority back - When process with reduced priority finished its activity and it uses less CPU than specified value, its priority will be increased back.

Show notification in system tray when priority changed: never, first time only, or each time - When show notification about changing of processes priorit.

 

Algorithm of priority tuning

1. If total load of CPU is greater than specified value (Total system wide CPU usage when start to limit CPU usage of processes), ATM looks through all processes and finds the processes to decrease their priority:
  • ATM skips following processes:
  • system critical processes (csrss.exe, explorer.exe, etc), nero.exe
  • processes which names contain "player"
  • processes with saved priority
  • processes that have windows in foreground
  • processes that were just started (10 seconds)
  • ATM finds the processes that use CPU more than specified value (Maximum allowed CPU usage per a process before reduce its priority).
  • If a process uses CPU more than specified value during few seconds, ATM sets its priority to Idle and shows notification in system tray (if specified).
2. ATM increases priority of a following process back:
  • Process uses CPU less than specified value (CPU usage of a process before increase its priority back).
  • Process has window in foreground.

 

Optimize memory

Free memory of processes that use more than __ MB of memory - AnVir Task Manager once in 15 minutes swaps half of all memory of processes that use more than 50Mb to disk. It may useful for example when you use Firefox.
