Upgraded to gutsy last night to check reported performance problems with tracker.
The difference in performance of tracker on Feisty and Gutsy is absolutely startling.
On Feisty tracker is very quick at indexing and does not slow down desktop responsiveness at all but Gutsy is the complete opposite and is barely usable (indexing appears to take forever and desktop pauses are all over the place - it totally sucks at disk I/O)
Its quite alarming cause I dont want tracker to be blamed for this. I checked trackerd with nice and ionice so theres no problem there
the good news is its not just tracker or gutsy that triggers this behaviour on recent kernels:
"Same sort of issues here, any heavy disk io (ie. pacman) completely cripples desktop responsiveness.
Only noticed after upgrade to 2.6.22"
some workarounds posted here:
I need to get onto the gutsy kernel guys to fix this pronto!
