What workloads do you run? I’ve got a 16GiB M1 mbp and a 2019 maxed intel and when compiling Java/sbt projects the intel is significantly quicker, albeit also much loader and power hungry.
Wow, based on the comments here I decided try out the native M1 builds of Azul.
I see a 4.1x speedup in compiling (including tests), excluding dependency resolution:
Azul Native M1 java JDK11:
./sbt "clean;compile;test:compile"
254.86s user
11.84s system
519% cpu
51.375 total
Azul java JDK11:
./sbt "clean;compile;test:compile"
490.04s user
59.48s system
269% cpu
3:23.81 total

Why? The Java community has only just been working on ARM64 support at all over the last few years, and it's still a little limited, and macOS ARM64 support is only out a couple of weeks and only from non-Oracle third-party builders I believe.
You have to install a Java VM compiled for ARM such as the one made by Azul. If you just get the openjdk from the main website it is compiled for Intel and will be much slower.

Depends which version you have installed. It's a taken a while for the native versions to reach the mainstream channels, so unless you've specifically installed an M1 build you probably have an x86 build being run under translation.
