Processor Bottleneck On Server

Good morning,

I've just updated my databases to V7.0 from 6.5. I am having some issues with CPU utilization after rebuilding the databases. I rebuilt the databases from scripts after modifying the scripts to deal with any SQL issues between the versions.

Symptoms:

When a bunch of stored procedures are executed the % Processor Time his 100% on a single processor system, the Processor Queue Length hits 13, the Batch Request/Sec starts at 20 and rises to 47 before dropping off, Context Switches go from 370/sec to about 833/sec before dropping off and there is an increase in page faulting.

My testing was done on a single processor but my real system is dual-300+ with 128Mb RAM. The database is only 40Mb and after running the index wizard there were no changes advised.

After reading a lot in help areas for MS and here I am not sure if this has to do with how SQL Server runs now (i.e. system configuration) or if it is a query issue with parallelism. I'm assuming query parallelism since the performance spikes occur when stored procedures are run. On a single processor is there a way to address this. Then, hopefully, I can deal with the real multiprocessor system.

Thanks much,

Don
