hi,

Why do you want to reduce CPU load?

if you are running at High "CPU load" at some random hours of the day and your application is working fine without any complaints from end-users, there is not reason to do so.

if your performances is really degrading, you must proceed systematically...

Maybe measureware can help you investigate further

kind regards

high cpu load is not always a bad thing. it could be your cpu is used optimal, if your machine is always using 30% of its cpu power that means it was over spec'ed by 70%! what a waste of money.

Hi Amitkumar,

it depends on what you need or what you want
As shridhar's mentioned at first you have to
collect some information from your system and
also as Dirk's mentioned high cpu always does not refer any going wrong on your system

Good Luck,
