Again in our staging environment getting ready for a release in production, we were seeing unexplained slow response times for our AgilePoint application when compared against production or development envs. After some digging we discovered that our production DB server that serviced the AgilePoint DB had twice as many CPU's as the dev DB server, and 4 times as many CPU's as the staging server.
What I didn't know is that in Sql Server you can assigned/limit how many CPU's the database can use. This setting is in Server Properties on the Advanced tab, and is called 'Max Degree of Parallelism'. Like many of the other settings with Server Properties in Sql Server, 0 equates to 'unlimited' or in this case 'all processors'.
