Hi, perf.haskell.org has something to say about these: Am Montag, den 06.03.2017, 15:45 +0000 schrieb Simon Peyton Jones via ghc-devs:
I’ve just committed this patch sequence fb9ae288088a3eabc4e1bb4e86fa473a3881d2e2 Make FloatOut/SetLevels idemoptent on bottoming functions
increases lambda runtime by 3%. Maybe an environment-dependent performance cliff, given that you did not report this regression in your nofib listing.

This is where most of the changes are: https://perf.haskell.org/ghc/#revision/9304df5230a7a29d3e992916d133e462b854e... 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.
