NOTE:
Under morphos 1.4.5 w OS4Emu the results are pretty much the same except of MIPS (522) and VRAM write (22mb/sec).

peg2@1.25, updated results with 0.37:

EDIT:

I ran ragemem under morphos 2.6 via os4emu and here's some interesting results:

As you can see , under morphos L3 cache is recognised properly and there's a big boost to RAM speed (except "tricky" which is significantly slower). The rest are more or less the same, but why isn't L3 cache recognized under OS4? MIPS are much higher under OS4 as well.
