Following are results of running "bonnie" using a file size of 256M.
Tests run on a 2-cpu system with 64M memory. Measurements taken
for 3 runs each using ext2 and xfs. For the most part, results of the
tests are virtually identical in using ext2 and xfs, except for:
1. sequential character input is slower in xfs by about 7-8%
2. Block write performance is slower in xfs by about 1-2%
3. XFS seems to use a little bit more cpu for block operations & rewrite.
