This corresponds to my experiences - 64 bits is slower, something I've ascribed to the cost of increased pointer size.
ghc unfortunatly also uses 64 bit integers when in 64 bit mode, so the cost paid is increased due to that as well, Also since each math instruction needs an extra byte telling it to work on 64 bit data so the code is less dense. John -- John Meacham - ⑆repetae.net⑆john⑈
