Basically I use my file system stress suite for DIY PC hardware test. Recently, I run this suite for different file systems under Linux. http://h2np.net/tools/fs-bench-0.2.tar.gz This test suite had been run for five file systems, ext2, ext3, reiserfs, xfs and jfs under Knoppix. See below for more detail of kernel and hardware information. Please note that my file system test suite IS NOT a kind of file usage simulation. This is a stress test for system and this IS NOT a final conclusion for file system performance test. But I'm interest in this results. 17GB partition test ( default setting ) Filesystem Total(sec) --------------------- ext2 15145 ext3 19435 reiserfs 13583 xfs 15269 jfs 20296 4GB partition test ( default setting ) Filesystem Total(sec) ----------------------- ext2 1968 ext3 2827 xfs 2180 reiserfs 1763 jfs 3123 --- Hironobu SUZUKI E-Mail: [EMAIL PROTECTED] URL: http://h2np.net --- Hardware, Kernel and Linux distribution information is as below. -------------------------( cut here )----------------------- # cat /etc/motd Linux Knoppix 2.4.5 #13 SMP Thu May 31 15:38:30 CEST 2001 i686 unknown The programs included with the Debian GNU/Linux system are free software; the exact distribution terms for each program are described in the individual files in /usr/share/doc/*/copyright.
