Public bug reported:
I'm posting the same bug as in
https://bugs.launchpad.net/ubuntu/+source/nautilus/+bug/47842 since it
still persists on Ubuntu Feisty with all updates.
As the author has very correctly described, this bug comes into scene
when deleting files on a directory with many files -- or -- when
deleting many files, period.
Those files were images on a local drive, I had preview turned on and I
selected a lot but not all files in the directory.
CPU was busy and deletions occured at a rate of 1 each 6 seconds (on a 1450
file count directory).
After some 500 items got deleted the average deletion time went down a little
bit to 3 or 4 seconds.
It was impossible to measure the correct O(n) since the times where not
continuous -- I mean, some times it deleted 10 entries in a second, some
other times a single entry took more than 10 seconds to delete.
I thought of some kind of mutex problems leading to temporary dead
locks, but since the CPU stayed at maximum all time I guess it may be
something else -- or simply a busy mutex waiting.
After 500 or so left entries, deletion happened like a flash until only
my 181 unselected files where there.
Thanks.
