Architecture (32/64-bit, x86/..., ...), processor, gcc version, OS, all 
play a role. Since ghc fares pretty well on 64-bit linux (David Terei and 
Don), both, via the NCG and via C, it seems its 64-bit code generator is 
better than its 32-bit code generator :(
And judging from David's 32-bit Windows timings, GHC's 32-bit code 
generator is better adapted to Windows than to linux, but its generated C 
code is horrible for Windows.
