Hi, perf.haskell.org has something to say about these:

Maybe an environment-dependent performance cliff, given that you did not report this regression in your nofib listing. > 995ab74b3c55fe3a0299bd94b49e948c942e76d6 Comments only No change reported. Good :-) > 1163f4f2fe9aabd722c963497c67c5f8c71ef71b Tiny refactor No change reported. > 9b2c73ea8082199245bfa6a28390b70b38f87fd1 Make TH_Roles2 less fragile No change reported. > 9304df5230a7a29d3e992916d133e462b854e55f Fix CSE (again) on literal strings This is where most of the changes are: https://perf.haskell.org/ghc/#revision/9304df5230a7a29d3e992916d133e462b854e55f There are some nice runtime improvements in cryptarithm1 (-12%), fasta, integer and scs (each -3%). But: binary-trees runtime increases by 5%. This was your daily performance weather report.
