More memory isn't the only advantage of using x86-64-compiled binaries over using i386-compiled binaries. x86-64 also has twice as many registers, both general-purpose and XMM (SSE), as i386. This means that the program can keep more variables in registers at once, without having to swap them in and out of memory. Regards Ingemar
