poor HD performance

[Lyle Chapman]

I installed FC3 the other day and found some really cool new features 
and the like but discovered a few bugs as well. I found HD performance 
is slow compared to FC2. I ran some copy tests between multiple disks 
(I have 3 fairly new ATA 133 drives and a brand new DVD burner) and I 
noticed that the processor usage skyrocketed (50%+ on a normal copy) 
and while burning to DVD is fine reading from it is severly slow.

I have checked hdparm and everything seems ok yet even though my 
machine is relativley new (3ghz, 2gb ram etc) it seems to really 
struggle with disk speed. I am also running the SMP kernel with 
hyperthreading turned on whereas in FC2 I was running the normal kernel 
without hyperthreading, could that have something to do with the 
problem. Has anyone got the same problem and or a solution. It would be 
most appreciated.


cheers,
