Thanks Linchi
I was reading this recently, do you have any feedback on it
"a single worker can service multiple users"
"you shouldn't increase max worker threads unless someone from Microsoft or
one of its partners has advised you to"
"things like DBCC SQLPERF(umsstats) should give a strong indication that you
are running out of workers before you even think about something like this.
Further, the fact that you're running out of workers doesn't necessarily mean
that you should increase max worker threads. "
"If you are truly running out of workers, it makes good sense to find out
why before you begin tweaking the system configuration."
