~127MB/s is the theoretical bus speed of PCI/33.  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?
