Excellent investigation. I have the first M1 MBP pro 13” and have done a lot of data stuff on it. My experience was also that python flew - cpython on the M1 being almost as fast as pypy on my 2019 i7 laptop - and java compilation was much faster too. The CPU is fast and the memory is really fast. The performance pain points though was anything involving containers, random 10-30 sec stalls in boot and app startup (I think it’s corporate firewall stuff) and a general preference I have for Linux desktop over OSX (yeah I’m a programmer).
