Public bug reported:
Binary package hint: gnome-system-monitor
For many minutes my total CPU load has been showing at 80-100% on both CPUs on
the 'Resources' display graph.
Yet when I change top-tab to 'Processes' and sort by CPU, gnome-system-monitor
is using c0-10%, gnome-video-thumbnailer is showing 0-20% (but averaging only
5%) and Firefox pops up ever now and then for 10% use (but low average). The
load averages for 1, 5 and 15 minutes are shown as around value of three
(shouldn't these have a percent sign shown after them, as I am only ASSUMING
that these are CPU % utilisation 'loads').
Anyway, I think there is a HUGE discrepancy in the individual figures
and the total, which should be EXPLAINED.
I have a 1TB external USB drive (NTFS) attached with 200GB of 700MB
movies on it, and another 500GB one (also NTFS) with 490GB of movies on
it, another of 200GB with 170GB of photos on it (mounted but not
accessed). I think the problem arose when I opened up a large directory
of large movie files... though it could be to do with the large volumes
being NTFS format?
My memory usage is 65% of 1.1GB RAM and 11% of 1.4GB swap file.
Nautilus was in 'file list' display mode (not thumbnails) though it
still had those tiny icons next to each listing.
When I changed the Nautilus focus away from the large drives, total CPU
usage (per Resources graph) dropped from 80-100% to 20-60%, (ie big
drop) yet the individual process CPU usage still showed c3% total, and
the figures were being updated as I watched (ie not 'hung').
Either way, when the total is very different to the sum of the elements,
it makes people distrust the whole system.... though it is not an
important bug (compared to the others I've recently posted regarding
Nautilus).
