Package: iceweasel
Version: 3.5.9-3
Severity: normal
For a couple months now maybe, I've noticed that Iceweasel is very sluggish.
The slowness seems to be local (i.e. unrelated to the speed of connection) and
manifests itself for example when moving the mouse horizontally across the
menubar, where the redraw of the menus has trouble keeping up with the mouse
movement, or when switching from one tab to another, where there's a clear
delay and I get to see the tab being redrawn about 0.5s-1s before the actual
windo's content.
This is on a 2.4GHz Althon X2 with 4GB of RAM, so it's not due to swapping, nor
to the machine being particularly slow.
The X server is using `nv', so it's not super fast, but it's been quite
sufficient until now and doesn't seem to justify this sluggishness.
It's even worse if I try to display from the same machine on some other
machine's Xserver (a Thinkpad X201s laptop on the same 54Mb/s wifi network):
such remote connection is completely unusable for iceweasel, whereas I've used
such remote display in the past (maybe a year ago) where the slowdown was very
acceptable.
I have tried "iceweasel -no-remote -P" and run with a brand new profile, and
have also tried with "iceweasel -safe-mode", but they still suffer from the
sluggish display.
The odd thing about it is that I use very similar Debian installs on many
machines and don't notice this slowdown on all machines. Also I've noticed it
at times on one machine, and then a week later it seemed to have disappeared.
So I feel like maybe it has something to do with the underlying libraries (poor
performance when some libraries and iceweasel are not upgraded at the same
time, maybe?).
I have not reported it until now specifically because it seemed somewhat
transient, and because I cannot really point to something very specific about
the sluggishness. But since the problem seems to still be around, and since I
recently noticed that the remote display is *really* slow, I felt it was time
(and important) to report it.
