That's funny, i switched from default to CFQ on my notebook which has a rather slow disk and it feels much better, especially when recovering from suspend to disk which swaps out a lot. It's possible it decreases overall performance, but it may feel faster sometimes. > There was a tip in the GWN about > turning on dir_index on an already formatted file system.

As a new ext3 convert (i happily used reiser3 for years before), any problems to be expected by doing so? Afaics it turns on B-trees which should have no impact on the safety of my data, right? Just want to make sure, i rather use a slightly slower file system than risking data loss. cheers, Wernfried -- Wernfried Haas (amne) - amne at gentoo dot org Gentoo Forums: http://forums.gentoo.org IRC: #gentoo-forums on freenode - email: forum-mods at gentoo dot org -- gentoo-dev@gentoo.org mailing list
