I haven't tried anything quite that low-end, but the couple of MIPS routers I've tried at ~400mhz take about 1 second for that step. I guess there could be something odd about the architecture that interacts badly with what libtommath is doing, or perhaps the compiler. The binary was built with optimisation enabled? Cheers, Matt
