CPU usage 50-70%

hi All,
we have cluster active-passive MSSQL 2000 Server + SP3.
The server experience high CPU usage, the counter % Processor Time is often
continually at 50 - 100 %.
Counter SQLServer:Locks:Lock Requests/sec is 60000 - 80000
Counter LockWaitTime(ms) sometimes 200.
Are above values high? I mean whether Lock Request/sec might generate such a
heave load on CPU?
any suggestions?
thx for help

Pit,
It depends. :-)
This could be perfectly normal. Then again it might not. These types of
questions can be answered very easily if you benchmark and baseline your
systems regularly. A third party enterprise monitoring tool would be
great for this. "high" or "low" are comparative terms to your normal
mode of operation. They should not be compared to mine or anyone else's
database system.
I would recommend you start collecting performance information so that
these questions can be answered more confidently in future. You could
also produce some nice graphs to show your boss how much of a proactive
DBA you are and earn some brownie points towards your next pay rise. ;-)
