Thanks, that should do it. I found the relevant script that mandrake executes if you've enabled optimisations in /etc/rc.d/init.d/mandrake_everytime. I'll either try to change the conditional to cause the script to execute here or just copy the relevant optimisations stuff (which looks very similar to what you provided) to rc.local. Thanks!

Just doing hdparm /dev/hda with no options will show you the paramters which the IDE controller is using for that disk If your disk is not using DMA then try entering: hdparm -d 1 /dev/hda and then do the -t option again. See if you get any increase in transfer rate. Also one worth trying is hdparm -c 1 /dev/hda which will enable 32-bit I/O. If you find that these improve disk performance you can put them in a combined form, i.e.: hdparm -c 1 -d 1 -k 1 /dev/hda at the end of /etc/rc.local. If you have more than one disk then try it on the others as well. ***NB*** It is possible that using these commands will lead to data corruption, although I myself have never had that experience. Also remember that if you are using SCSI disks and not IDE your device names will be /dev/sda, /dev/sdb etc. There are many other hdparm options covering such things as buffer size, block size etc. which I have to admit I don't really understand.
