Is the OS 64 bit? If so, make the 14GB RAM machine the database server. Mutliple cores is something FMS has been able to take advantage of for a long time now. 64-bit support makes that even more efficient.
The WPE engine should be on the machine NOT running the database engine in a 2-machine config. So together with the web server.
Thank you! Yes, Snow Leopard is 64 bit. I completed the upgrade, and all is running well.
I increased the database cache from 128 MB to 5G. We will see how that affects performance.
