Comment(by simonmar): nofib run today, comparing 7.0.1 and 7.0.1.20110210: {{{ -------------------------------------------------------------------------------- Program Size Allocs Runtime Elapsed -------------------------------------------------------------------------------- Min +0.4% -4.4% -2.9% -2.9% Max +7.9% +110.8% +65.9% +66.7% Geometric Mean +3.1% +10.3% +3.6% +3.5% }}} clearly this is quite bad, we shouldn't roll 7.0.2 yet. -- Ticket URL: <http://hackage.haskell.org/trac/ghc/ticket/4951#comment:4> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler _______________________________________________ Glasgow-haskell-bugs mailing list Glasgow-haskell-bugs@haskell.org http://www.haskell.org/mailman/listinfo/glasgow-haskell-bugs
