which is the best io-scheduler for FTP server ( with IDE-RAID card) ? Any other tweaks to increase io performance... And not to forget how can I select one on bootup ? can i change it after the system is running ?
take a look at:
/usr/src/linux/Documentation/block/as-iosched.txt
1) Kompile in IO-SCHEDs 2) use elevator=your-io-sched as kenrel param
Read also the little Help in Kernel-Config-Menu
Device Drivers -> Block devices -> IO Schedulers -> *
Of course there are many other things (some perhaps more important then IO-SCHEDs): filesystem, mount-options, the ftp-server it self!!
Sascha.
