if there's some amazing advantage to compiling all my code for 64 bits, please feel free to convince me. In private email. I think it more likely that I'm just being dumb.
I thought the default on slowarse was to compile for 32bit on x86-64.
Odd.. anyways, most of the time the performance advantage isn't large (much is lost due to the cost of dealing with larger pointers) but for some usage patterns the extra registers (and vastly cheaper syscalls on linux) do make a rather striking difference.
Generally running a mixed system is a pain because of the differing ABI causing a need for two versions of every library.
