Performance regression in ghcid
Summary
I use ghcid to run my tests, whenever I make a change, the delay between displaying "Running test..." and the beginning of the execution is much slower in GHC 9.4.3 (few seconds) than in 9.2.5 (almost instantaneously).
Steps to reproduce
- Clone the repository
- Run
ghcid --command='cabal v2-repl bug' -W -T End.dbg
- Change
src/M10.hs
for example - Toggle between
ghc943
andghc925
inflake.nix
Expected behavior
It shouldn't be that slow.
Environment
- GHC version used: 9.2.5 vs 9.4.3
Optional:
- Operating System: NixOS unstable
- System Architecture: x86_64
