Hello.

Is there any possibility of adjusting the harddisk behaveior in case
several processes access simultanously? It seems that currently most
time is spent in seeking, so reading two files at once gives not half
the data rate for each, but a very bad performance. any way to adjust
this? eg. giving the every process a whole second or something else?


thanks very much

Paul

Could go into system monitor and change the Nice rating for
different processes.

Sounds like you want a RAID really, maybe a 5 or a 10 with striping. If
you have SATA drives check NCQ is enabled. You could use hdparm for some
additional tweaks but the RAID is where it's at. Put a fan on them damn
drives too! :-D
