Using XFS, and kernel 2.6.8.
In the past two weeks I noticed that my PC load shoots up on anything that
needs disk activity. The CPU's are quiet during all this:
I/O contributes to load average. Nothing startling there.
top - 17:04:09 up 6:07, 3 users, load average: 2.25, 1.88, 1.37
Cpu0 : 10.3% us, 4.0% sy, 0.0% ni, 76.3% id, 8.7% wa, 0.7% hi, 0.0%
Cpu1 : 11.3% us, 3.3% sy, 0.0% ni, 70.4% id, 15.0% wa, 0.0% hi, 0.0%
It gets so bad that the mouse starts jerking!
Does anyone have some advice on where to start looking for optimizing?
(hdparm -t looks fine)
Could be the disk I/O is excessive swapping. Add RAM to fix.
Maybe DMA is off? Check with hdparm.
