The server was running WinNT 4, SQL 2000, and had one processor. We upgraded to Win2k, and added a 2nd processor. A couple jobs that we run daily are now taking up to twice as long to run. In Enterprise Manager, SQL is showing it's setup to use all processors. I just set each of the stored procedures for one of the daily jobs to be recompiled on their next execution, and I'm running the job manually right now, but this is basically a guess. What would cause the performance hit?
