Solar? This excellent performance is due to the CPU alone. However, the appropriate development tools have to be available (either bundled with the OS or installed separately) in order to compile JtR from source. Also, for "-sse2" builds, the OS kernel has to be aware of SSE (to save and restore SSE registers on context switches), so, for example, those builds won't work on Linux 2.2 or older kernels (without patches) even if the CPU supports SSE2. > I was under the impression that the high speeds on Macs were due to the > G4 and G5 cpus and that the OS had very little to do with it...?
