system idle process

[George2]

Hello everyone,


In your experience, what is system idle process doing? In my experience, this means system is (CPU is waiting for) doing some I/O,

1. like hard page fault;
2. waiting for information from network.

Are there any other cases which will cause system idle process happen and consume a non-neglitible percentage of CPU?


thanks in advance,
George

I don't have any proof about how windows "idle process" works, but I bet it would be doing os tasks such as scheduling or monitoring events and such - just a guess.

Thanks mac11,


It is appreciated if you could share any formal documents if you had found any. :-)
