2.6.24 kernel, also i see other people start to notice xfs problems too: <a href="http://www.t2-project.org/zine/1/">http://www.t2-project.org/zine/1/</a> ( i also saw other benchmarks)<br><br>it is second day that only thing i do is test different fs ( i need to choose which one to use quickly ), and when it comes to small files, reading them , listing large number of subdirs, xfs seems to have TRAGIC performance. i mean it can be like 100 times slower in some cases. ( you can see performance results of the other person in a link i pasted )<br>
<br>i will try 2.6.25-rc but i doubt it will bring back xfs to normal performance state. something is really wrong with xfs, and i just see it on my server for some time. how it is possible that my raid 0 made from 3 disks was slow, most processes were in 'wait' state (top showing a lot of processes waiting for hdd access) under heavy load, but... when i change from this array of 3 disk in raid 0 on xfs, to just ONE disk (should be 3 times slower) but on reiser4 with compression, everything is working like it was! i mean, reiser4 on hardware 3 times slower was doing the same in real life as xfs on better hardware. that's on server with more than 100 hits per second.<br>
<br>reiser4 is working third week without problems (but it is just a temporary solution, i had my own problems with reiser4 and i don't trust it enough to use it longtime)<br><br>anyways, i hoped btrfs will help me with this, but if there are going to be on-disk changes without backward compatbility, i think i will pass. <br>
