Commit f9720dc2eb (2021-03-24 12:55 UTC)
Platform Info:
OS: Windows (x86_64-w64-mingw32)
CPU: Intel(R) Core(TM) i9-7940X CPU @ 3.10GHz
WORD_SIZE: 64
LIBM: libopenlibm
LLVM: libLLVM-11.0.1 (ORCJIT, skylake-avx512)
Most of that time the progress bar was on 52/53, with only Flux still precompiling.
On WSL on the same machine precompilation finished in 59 seconds (but the environment was not identical)
