Hi,
I've recently implemented some benchmarks for my library, and while I expected a slowdown for 64-bit code, I'm a bit bit surprised by the results. In summary:
with 64 bit ghc 6.6.1, my benchmark runs in ~160 seconds with 32 bit ghc 6.6, it runs in ~ 95 seconds
here are my results (with reversed ghc versions) when running your code: with 64 bit ghc 6.6 254 secs with 32 bit ghc 6.6.1 146 secs Having noticed that the 64 bit ghc-6.6 is slower, I decided to install the 32 bit ghc-6.6.1 only.
