Actual throughput is much less than that, of course. But you're not on a 33MHz bus, you should be at at least 66MHz (and info in /proc should tell you). Given the lack of performance increase though, I'm guessing you're either pegging the bus or the CPU, not yet the throughput of the kernel itself. Does the program block in disk wait when running?
