OK, here are a couple of things to check.
Run "top". Is cpu usage (user + system + nice) often 100%? If so,
consider getting a faster processor. (If you're running a
"distributed computing" program like Gimps, stop it first.)
Is a task with "swap" in its name requiring a lot of time? If so, add
Do "hdparm /dev/hda". Here are my results:
multcount = 16 (on)
IO_support = 1 (32-bit)
unmaskirq = 1 (on)
using_dma = 1 (on)
keepsettings = 0 (off)
readonly = 0 (off)
readahead = 256 (on)
geometry = 16383/255/63, sectors = 40020664320, start = 0
Note that multiple sector I/O is set at 16 sectors, 32-bit I/O
support is on and using_dma is on.
Run "hdparm -Tt" to test the drives. Here are my results for comparison:
Timing cached reads: 1452 MB in 2.00 seconds = 724.51 MB/sec
Timing buffered disk reads: 124 MB in 3.00 seconds = 41.33 MB/sec
Run "prelink -avR". I think that Fedora 3 does this by default.
