My second observation is that the speed benefit of moving from a 68030/50 to a 68040/25 is minimal. Sometimes hardly noticed. Perhaps because of the particularly limited memory bandwith of the BPPC? (IF this is not just a rumour)
What tasks are you performing to observe this? When I switched from 030/25MHz to 040/35MHz the speed difference was obvious in CPU intensive tasks like file packing/unpacking, image conversion, etc. In straight WB use there wasn't much change (ie. it didn't speed up disk I/O much, and un-patched/un-optomised applications didn't seem to run much quicker.)
