thank you Manu, that's exactly where i got it from. My question is , in the article it says to check for values in the thousands for the CPU, i just wanted to find out how it is counted KB? Another thing, when i run this

select * from master..sysprocesses

where status = 'runnable'

order by CPU

desc

I get a lot of lastwaittypes SOS_SCHEDULER_YIELD

with cpus from 8k-10k, when i run the

DBCC INPUTBUFFER (spid)

then i get that is an rpc events, so these indicated that these stored procedures are taking high CPU Processor%?

Another question,

yesterday we were having slowness issues in the server and i run this

select * from master..sysprocesses

order by CPU

desc

*without the status filter

this is what i got:

CPU :127743

Status: sleeping

lastwaittype: MISCELLANEOUS

programn name: Replication-LogReader

cmd:AWAITING COMMAND

Could this be the problem? or should i ignore it since the status is sleeping?
