I was ecstatic that the bogomips increased by 187% (199.47). Recently, though, I heard of someone installing a JoeBoard into his StarMax 5000 and his bogomips being around 800. He mentioned something about a "Cache Profiler". It seems that BootX is somehow able to tell the kernel that there is a G3 in the cache and speed is increased greatly. The CPU on the StarMax 3000/160 motherboard itself (what originally came with it) is a PPC 603e. /proc/cpuinfo shows a 750 - which is good but the bogomips are nowhere near what this person reported. I do not use BootX for I prefer booting straight into Linux with Quik. Does anyone know anymore about this and if it's possible to increase performance more by somehow making the G3 quicker?
