Comment 19 for bug 144216

confirm this bug. My system is a brand new dell xps 1530, core 2 duo 2Ghz, nvidia 8600m gt, latest from hardy repo.

I can compare with a gutsy system on my three years old desktop, AMD64 with nvidia 6600GT. On this system loading, say, 6-8 tab at startup is slow, on the new dell is really fast but switching tab already loaded in memory is much more faster on the old system. On the Dell XPS takes more than a second to switch and ff is also slow in opening a new empty tab.
On the desktop with gutsy I am using FF3b3 (manual download) while on laptop with hardy is FF3b3 from repo.

on both system, compiz with emerald. Compiz 0.62 backported on gutsy, 0.7 on hardy.
