I attached nofib results comparing amd64 vs. x32 and i686 vs. x32; x32 is about 15% faster on average than either.
Impressive. So that's our memory/cache penalty for having all our data structures 2x the size on x86-64 ABI. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8287#comment:4 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
