Ron,

I would like to try this, however, since I'm sitting about 1000 miles
away from the server, tweaking things is not as simple as one might
hope. I would also like to understand what is going on before I start
changing things. If I can't get a satisfactory explanation for what I'm
seeing with current hardware, I'll have memory added and see what
happens.
