Upgrade simulator backend database and general performance
This is sort of a technical ask. Many times while running simulator - especially if it has been running for a while - the simulations slow down to a crawl. Seems like the execution threads are stuck waiting for some response from the backend database. It is likely that the cause is the old database engine (I believe SQL 2000). With our muticore CPU and multi GB RAM - we should be able to run 10 or 50 simulations at the same time.

yes, I see the same problem, the simulations end up slowing down to a crawl, and some times simply stop. I usaully exit the simulator and re-open to get the performance back up.
