You may want to look into using ReadAhead, some of the newer init systems are using it to decrease boot time.

deer, list! I currently try to minimize the application startup-time for my gentoo-laptop. Even with prelink it takes about one minute to start kde and all programs in autostart due to the heavy disk i/o load. In the last days I did some tests with taking a copy of my regular /usr (ext3) dir and storing it in a squashfs file. I then mount it as loopback device on /usr. (Leaving the original copy still intact but hidden.) Those are the effects I try to achieve: 1. The filesystem has no fragmentation at all. Files in my regular /usr dir are somewhat fragmented, but not too badly. 2. It's compressed: less disk i/o and more cpu load. So far the results have been promising. With the new squashfs I'm down to around 50 secs (-16%). But at the moment my benchmark methods are quite primitve. I simply have a stopwatch nearby and meassure the time from login to when the disk is idle again. I'm looking forward to some input on this. greets Roman
