Yes, the RC5 core is mainly assembly, so it's the same on both platforms, the OGR code is mainly C code so performace depends on the compiler. What compilers has dnet used on linux? I understand the prereleases for gcc v3 have the new p6 backend that was sponsoured by intel, can produce much faster code i hear.
