[PVFS-users] Bonnie benchmarks

[Kevin Makles]

Hi,

I've been running a few benchmarks to test out PVFS and found some strange 
results when I ran the Bonnie Benchmark.  The strange results only occur in 
the  Block write benchmark.  Here are the results from a 4 I/O node system 
with 100Mbit ethernet interconnect using version 1.4.4 of PVFS.
