Firefox 2.0 on edgy slow?

Is this happening only to me or have others noticed that the new Firefox 2.0 on Ubuntu Edgy is just unbearably slow when opening a multitude of tabs?

It actually brings my system to a crawl rendering it almost completely unusable until it is, ages later, done with whatever it is doing (e.g. opening a tenth tab or so).

Also, while it is open on edgy, switching to other applications, even other desktops, causes a little lag with mouse movements, a quick freeze of sorts.

I also suspect edgy as a whole to be slower than dapper. What do you think?

I rebooted to Fedora and now back to Edgy again and for now it works fine as well. I am not sure what's the deal.

Maybe it's just a memory issue. I don't have much of it (256 minus 16 MB currently for on board graphics since I still didn't get my ATI card :\ ). How much memory do you guys have?

If it is a memory issue and edgy turns out to be more memory hungry I don't like it.. it shouldn't grow in requirements so much.

I started opening more and

I started opening more and more tabs to test it out. It all worked alright and the speed was normal until it suddenly, out of nowhere started scratching the disk again like crazy and slowing everything down to a craw (including mouse movements).

In this state it is hard and incredibly frustrating even to just switch to another desktop where the terminal is open, open a new terminal tab, enter the top command to see what's going on. I did that and noticed no strange processes. Firefox shows to be using 20MB and that's the most of it.

But one thing that was weird is that swap was all on zeros. I suspected swap isn't turned on and then ran sudo swapon /dev/hda1 and all of a sudden the disk scratching and slowdown came to a stop. All works fine now.

So apparently for some reason swap is turned off by default after boot or it drops on its own. I can't be sure right now. I did select a swap partition normally on edgy install.

If it is somehow turned off on boot then I can well understand what's happening. I run out of memory (or get dangerously close to it), but it doesn't have a normal fast swap filesystem to use to help itself.

But if it drops swap on its own then I have no idea what's going on. Gonna have to check this all out.

Firefox 2.0 actually

Firefox 2.0 actually appears faster now that swap is on. Hmm.. liking edgy so far now.. Smiling
