Ask Sam Jordan, or Haage&Partner. He decided that his emulation
makes no sense in its current state.

Not really. In opposition to MorphOS the whole AmigaOS system has
to be emulated. A 68040/25 is no fun when you're used to a 060.
Certainly, PPC applications will be a bit faster.

I didn't run any benchmarks, but did it now: I used the HeapSort
benchmark and got the following results for an array size of 8000:
BlackBox: 6.47 MIPS
MorphOS: 6.69 MIPS
For comparison, my real 060/50 does: 26.49 MIPS.
