Sorry, I'm not sure what exasct build number i'm using, it's absent from the 
lower right corner where it used to show me. But I'm using the build from this 
directory on the FTP: 2000-07-05-09-M17

It seems that a large number of Animated GIF's seem to slow down the animation 
of eachother. If you view a page with a single animated gif (or scroll down to 
the bottom of this website so only a few of the GIF's are showing), they appear 
to animate much faster, as they do in IE (in NS4 they also animate faster than 
Moz but not as fast as IE) ...

However at the middle/top of this page where there's so many in the same place, 
there is a huge slowdown between frames of the GIF images. Compare the IE page 
side by side with the Mozilla page, and its very apparent theres a problem in 
how Mozilla is handling large numbers of animated GIF's.

I'm sure this affects other "dance" sites in the same manner.
confirming using 2000070713. there is undoubtedly some performance work needed 
for many animated gifs near each other

Verified Win 2000122105. I have a large (~ 450kb) animated GIF, it runs trough,
pauses for 2 sec and then restarts (numbers are for looking at just the gif, no
HTML embeddig the GIF, my CPU is an Athlon 1Ghz).

Program
	CPU	Notes
=======         ===     =====
IE 5.5		24%     animation is smooth
Moz 		100% 	machine feels bogged down, image flickers at restart
ACDSee 		2%	image viewer prog but interesting for comparison

All pnunn bugs reassigned to Pav, who is taking over
the imglib.

I can happily say that with the landing of libpr0n, moz uses half the CPU
(12-14% on the same machine which gave the results in earlier post) of IE 5.5 on
my machine when showing a big animated gif. Should this be marked fixed?
yeah, this is fixed with the new imagelib.

With 2002022103 this is still very apparent. One needs only compare IE & Moz
side by side to see the tremendous slowdown.
