I've made some time to work on the Amiga Squeak VM I started many years ago.
The screenshot above shows it running on its own 8bpp screen on an Amiga 1200. This Amiga 1200 has a 40MHz 68030 processor, and you can see the benchmarks.
In comparison, my Core i5 MacBook Air running 64-bit Squeak 5.1 with a recent Cog VM gets these benchmarks:
'2,000,000,000 bytecodes/sec; 190,000,000 sends/sec'
Features recently enhanced in the Amiga port:
Most development has been done in this round on MorphOS 3.10 using SAS/C 6.58 and CygnusEd 4.22.
