CPU usage in Task Manager

[Rob graham]

In Task Manager we are shown certain levels of CPU usage. A figure of 95 may
be an example. What is this 95? Is it percentage of CPU being used or is it
some other unit?

Yes the precentage.

 

[Bob I]

Task Manager Help describes the units and the measurement interval.

 

[Rob graham]

Yes the precentage.

OK, so the time of writing I have *svchost* on 02 and *system idle
processes* on 98. I realise that this is not 98 per cent of the CPU's power,
just 98 percent of what's being used at the moment but why does *system idle
processes* always seem to use so much CPU?

Idle means the CPU amount left for work.

I have to chuckle at this one. It's a process that occupies the cpu
when the cpu isn't doing anything else. So at 98% for system idle the
system isn't doing anything.

That process actually cools the processor, without it, the proc would get
very hot

 

[Rob graham]

Great. Thanks all.
