[Vm-dev] Squeak on BeagleBoneBlack (ARM FFI)

[Douglas McPherson]

The tiny benchmarks on the BBB are

67015706 bytecodes/sec; 3536215 sends/sec

and for the RPi:

30360531 bytecodes/sec; 1971110 sends/sec

So the BBB seems about 2x compared to RPi, at least for these tests. 

What is the nature of the BitBlt enhancements? Would they be easy to apply to the ARMv7?

Thanks,
Doug
