The Environment

All tests performed on the same machine Dell Poweredge 1650 with 512Mb of RAM and 1Gb of swap.

DB-A:/ # cat /proc/cpuinfo
model name      : Intel(R) Pentium(R) III CPU - S         1266MHz
cpu MHz         : 1258.261
cache size      : 512 KB
bogomips        : 2510.02
I each time ran the tests on 4 different filesystems , XFS, JFS, ReiserFS and EXT3 on a default Suse Suse 8.2 install with Linux 2.4.20-4GB.

For the MySQL 3.23 tests I used a different filesystem for each tests, with the same size but probably a different location on the disks. For the MySQL 4.1 test , I each time used the same partition, but freshly reinitiated with a new filesystem type. The results are below.
