sp_who2 output
EJO
In query analyzer and profiler, there seem to be system processes that
are generating high cpu time and disk io. Well, I guess the short of
it is that I am having a problem interpreting what I am seeing so that
I can take the next step in corrective action. There are also several
domain controlled logins that appear to be on the same host name, at
the same time--these are laptops, not terminal servers--why would the
system be reporting such a thing?
Here is a sample of the output from sp_who2:

They don't look particularly high to me. CPUTime is in milliseconds, so
10 seconds in five days is not a lot. And 2400 disk IO for the checkpoint
process looks like a calm system to me...

An application can set the host name when the connection, and can
blatantly like if it wishes to.

sp_who2, I thought I always had excessive times--which you are
indicating it is not. I guess I'll be looking else where for my
performance issues...as I still need to finish going through the
profiler output.
Once again, thanks for your assistance.
Eric
