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
