    Try using a file larger than 160 megabytes to negate any effects
of a file system cache.  None of the drives you used in the benchmark
can sustain anywhere near the read throughputs you are getting above.  :)

    Interesting to note that bonnie reports higher CPU usage on a big,
bad Sparc20 than on a lowly 486/66 FreeBSD box (16 megs, 5400-rpm
Quantum Empire 1080, NCR53c810 controller).  :)
