But the numbers are : fairly consistant across the different degrees of old crappy hardware I : have. So you are seeing a about an hour slowdown (16% slowdown on 6 hours is 1 hour) from before/after? Or are you seeing an hour slowdown from 4.x -> 5.2-beta? Also, so we can characterize where the suckage happens, how much RAM/CPU does your system have?
