High Cpu, Low Speed
May 17, 2006i have high cpu problem. i don't know why many .net sqlclinet data
provider and IIS hold so much cpu resource. by the way, memery
condition is normal.
when i restart sqlserver, from windows task manager, i see the cpu time
of sqlserver.exe process is low, but it grows gradually, and in two
days, it can grow to as high as 2:xx:xx.
any one can tell me why .net sqlclinet data provider and IIS hold so
much cpu resource? and why cpu time of sqlserver.exe grows gradually?
thanks a lot.
below is the part of a trace report:
