On CentOS 5.0, a had the same benchmarks and now, EXT3 and XFS seems
to had better or equivalent performance on Read and Create Random
files. One of this tests, using bonnie++, show this:
# bonnie++ -d /mnt/sdc1/testfile -s 8192 -m `hostname` -n
50:150000:5000:1000
bonnie++? Not appropriate. Try this:

And add JFS to the mix. You will be surprised.
I already done tests with fsbench and the results on CentOS 4.5 were
equivalent: the performance of XFS was much higher than EXT3.
Then, i retest using fsbench, bonnie++ and iozone on CentOS 5.0, and the
results now show the EXT3 (dir_index, noatime) with performance similar
to XFS.
Say....how do the numbers on Centos 5 compare with Centos 4.5? Did XFS
loose performance?
