Hello Shane, A couple things to note:
1) Cold Fusion MX Professional (not Enterprise) will only use one CPU. If you want to take advantage of both CPU's on that box then you will need to use Cold Fusion Enterprise. 2) Since you're only hitting a "hello world" page, I find it highly unlikely that postgresql would be what's causing your problems. Also, postgresql is a multi-threaded database, so it *should* be able to utilize both CPU's on that box. That said, if CFMX is maxing out one of the CPU's on your system, postgre should have no problem utilizing the other CPU. 3) A few questions: Have you checked out your memory usage while this is happening? How about hard drive usage? Is hard drive usage spiking as well when you run these tests? What are your JVm memory usage settings configured to?
