high cpu, low speed

[sp_who2]

i 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:

If i recall correctly, CPUTime is the cumulative time spent. It is NOT
the amount of the CPU that is currently being used, but rather the
amount of cpu time that has been used since the process started.
