Cache compiler after stdlib to speed up tests #450

Closed b-studios closed 1 month ago

b-studios commented 1 month ago

This Draft PR experiments with caching the compiler after compiling a trivial file.

On my machine, this way I can run all tests (except ML) within 55 seconds (they run in parallel, though). For the ML backend the performance of mlton is still the limiting factor.

Apparently it did not solve the Text File Busy :)

java.io.IOException: Cannot run program "/home/runner/work/effekt/effekt/./out/tests/effekt.chezschemelifttests/patternmatching": error=26, Text file busy

Overall the caching is quite successful: it brings down the CI times from about 18min to roughly 8-9min where most of the time is spent in the ML compiler.
