It should be `MUT elapsed / Total elapsed = 56.484 / 58.075 = 0.972` but it looks like `MUT user / Total elapsed = 29.344 / 58.075 = 0.505` Looks like the code at https://github.com/ghc/ghc/blob/a88bb1b1518389817583290acaebfd6454aa3cec/rts... uses wrong numerator for elapsed value. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/12424 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
