If you pay close attention to these figures, it shows that Vue is having a hard time with Pentiums. Notice louguet's times between the 3 gig P4 and the XP 2400. That's just way too close for machines with such differences. louguet, if you have a chance, can you post your chipset and bus/ram speeds for you XP 2400 and 3 gig P4? Does anyone have an XP 3200 machine running on a 400 meg dual channel buss? I bet any amount of money that system would eat the 3 gig P4. There's just something that's not right with Vue and the P4 systems. What's not certain is whether it's a CPU issue, a chipset issue, or both. I should add that all the other software I've tested so far show significant speed gains on my 3.2 gig Prescott system with 2 gigs of ram, as of course they should.
