(I'm not the original poster. I'm not going to do a clean install; I
use my laptop for work and don't have time to reinstall from scratch).
I'm running Gutsy, and generally keeping up with updates. As soon as
trackerd was installed, I noticed my system became unusable.
My laptop is a Core Duo 2GHz with 1GB RAM. Kernels 2.6.22-{7,8,9}.
The only way I can do any work is killall -STOP trackerd. I've got it
set in "Indexing Preferences" to the slowest setting. I have free RAM,
and the CPU is not particularly busy. The disk activity monitoring
applet shows occasional but not constant activity, but the disk LED is
constantly on.
Yet, the desktop is sometimes unusable, and always affected, while
trackerd is running. Dragging a window may take up to 10 seconds before
it moves. (I'm _not_ running the 3d window effects, by the way). Menus
can take a second or two before appearing. Apps take 5-20 seconds to
start, when before they'd be a second or two.
It feels exactly as though the system was swapping heavily, but it isn't
swapping. Only 42MB of swap space is used, and that's probably due to
entirely idle pages.
It's weird that this happens with free RAM, little CPU used, and little
disk activity according to the applet - and not a lot of seeking sound
from the disk, either, although the disk LED is always on.
I am guessing a kernel bug or scalability problem is involved.
Something to do with VM or I/O scheduling. Perhaps made worse by the
way trackerd spawns lots and lots of large processes, and the way they
don't use O_NOATIME.
I have set "noatime" in the mount flags now. This improves desktop
responsiveness enormously, but it is still noticably laggy, so I still
do "killall -STOP trackerd" when I want to get some work done or start a
new app.
It's taken about 4 days now, and still hasn't finished clobbering my
laptop. Shouldn't it have stopped indexing by now?
