Some time (probably some months) ago I occasionally noticed
very high memory
usage on my CURRENT notebook. I don't think this has always
been the case,
but I'm not 100% sure.
For me, this is reproducable very easily if I view some
large (3000x2000
pixels) .jpg files in konqueror.
On my 6.2 system, memory usage goes up quite a bit while
decoding the image,
then it drops a bit. If I close the image, memory usage is
normal again.
On my current system, sometimes memory usage goes up very
high when opening an
image and doesn't go back to normal, even if I close the
image. It only goes
back to normal if I close konqueror.
Note that I see this also with a gtk app, so this is not a
KDE bug. Also, at
least in konqueror, I can reproduce this with .png files, so
it's also not a
jpeg library bug. CURRENT and ports on both systems are up
to date.
I don't really know what's causing this problem. Maybe it's
related to
jemalloc, but I'd be surprised if no one else has noticed
this before.
size/res values reported by top
6.2 desktop pc with nvidia binary driver
konqueror 40M/30M
CURRENT notebook with the i810 driver
konqueror 290M/250M
Any clues or more information needed?
Thanks,
Stefan
