Indeed, with `-fllvm` the run times are much more consistent across versions of GHC. || version || run time (sec) - bangs || no bangs || ||7.4.2 || 4.99|| 19.67|| ||7.6.3 || 4.99|| 19.30|| ||7.8.4 || 4.80|| 4.80|| ||7.10.1 || 4.97|| 4.97|| In this case, do we keep this bug open? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10400#comment:4 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
