Richard not 100% positive but it very well could be the older CPU being the limiting factor here. Especially since you see how fast your laptop loads it.
With my previous build a P4 3.0 GHz, it took over 30 seconds for CS3 to open up and Bridge even longer. Now as noted earlier with the E6700 Dual Core chip its a matter of 5 seconds and even faster once the app has been loaded.
