Why is Opera faster?

[deech-2]

Hi all,
I have been using Conkeror for the past year and I love it! But I recently tried Opera, and while I like Conkeror better for usability, Opera is much faster. I tried tweaking all the Firefox settings, using FasterFox etc, but without much effect. Has anyone else managed to make Conkeror faster?

thanks ...

As far as I know, Conkeror can only be as fast as XULRunner/Gecko lets
it. This is the fundamental (if not the only) cause of the slowness.

As a sidenote, a few Conkeror developers are working on a WebKit-based
browser codenamed Minno (http://sourceforge.net/projects/minno/) which
will use Gambit Scheme instead of JavaScript and will probably be
lightning-fast in comparison. We are all looking forward to seeing
where that project goes!

That being said, I'd be surprised if the developers at Mozilla aren't
investigating ways to make the platform as fast as it once used to be,
so all hope isn't lost, I think.

For one thing they are completely reimplementing the javascript
engine, much like V8 of chrome fame.  I would hope that when this
enters the mainline (unless I am very out of date and it already has)
it should improve everything javascript run.  I am hoping that they
will also be supporting multithreading etc. as V8 does.  Hmm, come to
think of it, I wonder why they are not just using V8?  Anyway, as
everything conkeror is javascript, it will hopefully lead to a huge
improvement.

That said that minno project sounds interesting.  Webkit is very nice,
and very, very fast.

This is probably quite subjective, but it seems to be my experience
that Conkeror is quite a bit more nifty under GNOME than it is under
Fluxbox. I don't understand why, but it could be something to do with
GNOME using gtk engines which perhaps involves pre-loading various
libraries and stuff... I don't really know.

I think the new engine is already out, but I can't remember which
versions of XULRunner it comes with. I'm using 1.9.1 and if I'm not
mistaken I am using the new engine.

According to some performance tests, Tracemonkey (Mozilla) is faster
than V8[1]. Also, V8 is under some BSD license and I'm not sure if
that's compatible with Mozilla's "tri-license" that Wikipedia says
that Gecko and XULRunner have.
