Thanks, that's good news. I can't use an insider build - I need to be on
standard Windows in order to support our customers. The latest reports
in the GitHub issue seemed to indicate that the slowness is still quite
significant even on insider builds. I'm glad to hear you say that this is no
longer true. I am looking forward to regular GHC binary tarballs working
normally on regular WSL sometime in the near future.
