Comment 18 for bug 131094

I think there are two separate issues here

1) something in old tribes affects disk access (HAL or UDEV?) and on some occasions they persist when upgraded and only a fresh install cures the problem. This is what affected me and all disk IO read and writes were affected very badly even without tracker running. This only happens rarely as only a few people had this...

2) Ext3 write performance is very poor on both feisty and Gutsy - as soon as pdflush starts it tends to hog the disk. Putting $Home/.cache/tracker on a different FS like XFS improves things a lot (I only did this on feisty but not gutsy)

if default pdflush params have changed on gutsy kernel that could also affect write performance negatively.

 Another thing is my hard disk is whisper quiet on feisty but extremely noisy on gutsy - I had to hdparm to lower the noise. WOuld be nice to make it quiet by default too especailly as tracker makes it very noisy at times
