[gentoo-server] vmstat cs and in

[Richard Broersma Jr]

according to man vmstat:

   System
       in: The number of interrupts per second, including the clock.
       cs: The number of context switches per second.

1) Does anyone have a "layman's" explaination of what interrupts and context switches are?

2) How high can these numbers be before a system admin should start to worry about preformance?

3) what are the options to reduce these number?


Thanks for any information.

Regards,

Richard Broersma Jr.
