Hi Bob --

It should not be that much slower:

macMini (Oct 2020) macOS Big Sur 11.6.2 Chip: Apple M1 OSVM: 202112201228 (arm64) 4,400,000,000 bytecodes/sec; 330,000,000 sends/sec OSVM: 202112201228 (x64 via Rosetta) 3,500,000,000 bytecodes/sec; 270,000,000 sends/sec

The OpenSmalltalk VM can be build directly for Apple's M1:

Best,

I've been moving some code I wrote from an Intel mini to an M1 mini. It's running a lot slower on the M1, so
1. is that expected?
2. is there an M1 vm ready or about to be?

Thanks,
Bob
