Hi All,

I have a Windows Server 2003 SO2 running in a virtual
machine. I have 12 available cores. I gave WS03 8 of them.

Just out of curiosity, is there a point were too many
cores slow WS2003 down?

Many thanks,
-T

Sorry. I meant WS2008.

Cores doing what? The software generally won't spread a limited number of
tasks across multiple cores. It's up to programs that can use the threads
to start seeing greater use of multiple cores. What apps are you running on
the box?

Mainly Quick Books.

I have run SQL 2000 server on a Win 2003 server where having 4 CPU's
with a total of 8 cores caused queries to fail by blocking each other.
With that said, since we could not change the queries we limited
parallelisms for SQL and the queries flew (were fast).

QB doesn't really have a real database. Since the server component
doesn't really do a lot, on the server, your delays will be file sharing
as well as workstation performance. That's been my experience since DB
2003 to 2010.
