Each result is an average of 5 runs. For Reiser4 i used default mkfs options and -o formatting=extents For Reisefs i used default mount options and -o notails Assuming that default behavior of bonnie++ is to use twice the RAM of the server, no reboot was done between consecutive runs Bonnie++ was run like this : bonnie++ -x 5 -d bonnie Hardware: Dell PowerEdge 2550 1GHz SMP, 1Go RAM, SCSI 15K RPM U160 Seagate Cheetah X15 Disk Software: Debian Sid + 2004.07.02 Reiser4 auto snapshot ( 2.6.7-mm4 ) .config file available here if interested: http://philou.org/linux/reiser4/config-2.6.7-mm4 Biggest regression seems to be in deletes. I will gladly redo my benchmarks if you feel i did or missed something obviously important, or you'd like me to test other FSes as well Comments are welcome.
