High Context swtiches/sec

We have context switches/sec around 18000 on an 8 way CPU . I am using SQL
2000. Is that good or bad ?
If bad, what can i do further to investigate or reduce it
ThanksIt's not horrible but could probably be better. I would check to see how
your disk queues and cache hit ratios are.

High %privileged and interrupt time

Had a high CPU on my SQL Servers and on further investigation, it appears
that the % privileged and interrupt time were high and not user time.
What should I account for such behavior especially if it occurs on many SQL
servers at the same time ?
Cannot find anything odd in the event or SQL Logs.Hi

You can also look at interupts/sec. If you are getting excessive number of
interupts it may be a disc issue so also look at Physical Disk counters.
