Sarge with mozilla-firefox 1.0.4-2

I should note, however, that Konqueror and Mozilla also seem slow on
that page.  I tried it with IE on WinXP (did't have Firefox there), on
a slower machine, and it was *much* faster, so maybe X11 is part of
the problem.

Yea, or even compare window managers. I'm using IceWM here. Firefox is
still back at 1.0.3 on my computer, installed from a tarball. Firefox
seems to be the same speed as Galeon and Mozilla (only other 2 I use
with regularity).
I will also mention that it is very rare for me to use Windows these
days, so I may not know what 'fast' is for a web browser. (But I tend to
doubt that. :-)

The difference is measurable, not subjective.  To prove it, I ran top while
slowly scrolling with the mouse pointer on the "slider" on the right margin.
Moving the slider slowly, I was able to max out a 1.5GHz CPU with a Radeon
AGP card.  Slashdot, with a similar-looking page, uses only about
25% percent of the CPU cycles in the same test.  This was with Mozilla,
but as I mentioned before, I get similar results with Firefox.
