Ok, thanks guys. I think a part of it is my system - currently just a Core 2 6600 w/2GB of ram. The machine gets pretty lagged at times. I'll have the parts here tomorrow to put together a new QX9650 quad core / 4GB DDR3 / 2x8800GTs and a pair of solid state drives....hopefully this will be enough to do 5 clients smoothly without lag.
