Turn down the stage2 optimisation, and turn off the docs:
GhcStage2HcOpts = -O
...but doesn't that compromise the compile-time metrics collected by nofib about GHC's performance?
I think Johan is interested primarily in runtime performance, but yes if you care about compile time then it's better to leave GhcStage2HcOpts at the default. Cheers, Simon
