I've ran some XBench 1.1.3 comparisons between 10.3.3 and 10.3.4 on my iMac DV 400 and came up with some interesting results. Namely, the floating point basic test seem to be approximately 30% slower on the new OS while all the other CPU benches are a little faster (5% or so). Also, the random disk tests are down about 30% across the board while sequential tests remain about the same. OpenGL seems to be down a bit too but I'm not sure whether its significant or not. Ran both tests twice on each OS to make sure that everything was cached up. Other variables: Norton File Saver installed but not enabled, journaling off, 576mb RAM, 7200 RPM 40 gig drive (not stock 10gig).
