Changed App Server from single to dual processor virtual machine; Now queries take twice as long! Why?

OnBase 13 SP2

We have our Application Server on a virtual server. In an attempt to improve performance, we reconfigured the virtual machine from a single processor to dual processor. Instead of improving performance, the opposite has occured. For example, queries now take TWICE as long to return the hit list.

While I'm waiting for help from my support, can anyone give me any ideas of why performance got worse? Any ideas of what I should check?

It's been a bad day.........

Thanks for any suggestions.

Still having performance problems after changing server back to single core AND doubling the RAM. It's slightly better than with the dual core, but still way slower queries than before we converted to the dual processor.

What could cause the performance to be slower now than it was orginally even though we now have twice the RAM? What could get "messed up" just from converting to dual processesors and back to single again?

Thanks for any suggestions-
