Mozilla Very Very slow in rendering

[Mark C <lists@funkypenguin.net>]

Hi,

I'm not sure if its me going mad, but every version of mozilla using xf
build from testing/unstable seems to render very very slow, in terms of
UI and web pages,
but on the same box under redhat mozilla loads and renders fine 
(just everything else in rh is slow)

This is the same for galeon, and firebird, are there any debian specific
patches that may cause this slowdown?

FWIW, I'm runnnig 1GB DDR ram and a Athlon 1.3 Thunderbird CPU, with an
ata 100 hdd.
