(Speedup - so **higher is better**). Last I checked nofib performance was neither here no there in terms of runtime. (Slightly slower on sandy bridge, slightly faster on haswell). Compile time with the patch went down on both though. || Library ||Sandy Bridge (Linux) || Haswell (Linux) || Skylake (Win) || || aeson || +2.6%/+2.8% || +2.3%/-0% || +1.2%/+1.0% || containers || +1.4%/+1.2% || +1.1%/+1.7% || +1.7%/+1.0% || megaparsec || +3.2%/+3.6% || +13.6%/+13.7% 1) || +8.0%/+6.6% || perf-xml || +0.2%/+0.0% || || +1.1%/+0.8% || text || +3.0%/+3.0% || NA || NA || Vector || +2.5%/+3.6% || +2.5%/+2.9% || +1.3%/3.8% 1 ) Inflated by background noise. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15124#comment:9 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
