I am working to get our team on SSC 18.104.22.168 / TFS 2010 and I am having pretty severe performance issues with our largest db of 8000+ objects. I am not linking static data yet.
It took over 20 minutes to bring up the get latest screen and the breakdown is roughly as follows:
~4 minutes "Waiting for pending operations" (moderate to high ssms.exe cpu)
~3 minutes "Registering..."
~8 minutes "Calculating changes" (low cpu)
~6 minutes (? maybe more I walked away for a while) "Accepting updates from source control" (fluctuating cpu usage from 1/4th of a core to 100%)
I watched ssms with procmon and at one point (I think registering or "calculating") it was writing many small files to \\local settings\\temp\\Red Gate. The files were mostly 0 k and at most 18 mb. It didn't seem like it should tax the system so I am puzzled.
At first I suspected the VM client that I was using but I switched to a physical Core 2 duo 2G of ram with similar results (VM had 3). SSMS eats 800mb or so during these operations so I might slap some more in and retest.
Checking for commit takes about as long.
