I'm not complaining about the speed of the current OS X but I do need more RAM (stuck with the 256 my 933 G4 came with ). There are, however, people who complain about it on these boards. Did they mention anything about a speed boost @ WWDC?

The aforementioned Quartz Extreme, which will offload Quartz compositing to your video card - the whole interface will be rendered in OpenGL!
There is also a roughly 20% all-around speed boost predicted, and a new, faster, multithreaded Finder with built-in searching.
Closer to release, 10.1.5 is rumored to speed up WebDAV (iDisk) and other networking.
Jaguar lands at the end of summer. 10.1.5 lands sometime before then. In the meantime, if you plunk another 256MB or more into that tower, you can roll your own speed boost.
NO, actually conservative estimates at this time suggest that Jaguar will actually slow OS X to a COMPLETE crawl, an improvement over the I-am-dragging-my-crippled-ass-across-RAM crawl we are all accustomed to.

My speed boosts amounted to more modest gains of ~5% with gcc 3.1. not that I've been playing with gcc 3.1 for a few months now...</strong><hr></blockquote>
I'm not expecting that number to come from gcc alone.
btw, I've been seeing this magical "20%" faster a bit here and there... is this just wishful thinking or what? Where do we get these sort of numbers from?
Even WITHOUT quartz extreme, quartz is a LOT LOT faster.
With it, well, I haven't seen that
So if your in the same unsupported boat as me, don't worry! Jaguar will still be a LOT LOT faster. Many on unsupported quartz extreme machines say it is 90% of OS9 speed. I'd say that would be.... dead on. X currently feels about 50% in 10.1
Jaguar is a lot faster, even if you can't use Quartz Extreme. I only have a Rage 128, so I can't test QE, but the whole damn thing feels a lot faster, much more solid and polished. From my use of it over the past couple of days, it's really getting to the point where you shouldn't be able to complain about speed anymore.

If it is, I wouldn't expect to feel much difference--"20%" isn't much--(except with the Finder--MUST be better?) that you won't already see if you doubled your RAM and did a little tweaking with maybe priority levels of the WindowServer & Finder and turning window compression on.
Okay, I bootlegged Jaguar to see how it stacks up at this point.
On a Power Mac G4 dual 1 GHz with a Radeon 8500, window dragging has definitely improved. For a window that was nearly full screen, it was using about half as much CPU compared with 10.1.4.
However, things the UI seemed a bit slower on an iMac DV SE 500 MHz. Application start-up times seemed faster though. I should install 10.1.4 back on the iMac to see if it wasn't just my mind playing tricks on me.
?I get the impression Apple said 'we?re never going to let the user see the spinning cursor again',? said one Jaguar user, speaking ? as all others were ? on condition of anonymity. ?For all practical purposes, it?s been eliminated.?
Ah, but not quite, it seems. The notorious spinning CD-ROM cursor, also known as the beachball of death ? and a legacy from the NeXT era - has been laid to rest. The wait cursor has morphed into an animated Aqua blob. If you?re unlucky enough to catch it, that is.
Whether starting applications, switching applications or simply scrolling, the system remains responsive, say users, and one reported several hours use on a G3 system without seeing the wait cursor once.
<hr></blockquote>
Hopefully, I can say the same on a iBook 600. The "several hours use on a G3 system" is encouraging.
I also think that, in addition to the removal of debug code in certain places, much of the speed-up comes from good ol' profiling to see where the bottlenecks are, then optimizing the code on a lower level (perhaps even to the assembly)
This is the sort of thing that a really good development team will adhere to. To quote from Joshua Bloch's Effective Java (a GREAT BOOK..much in the style of the vastly popular Effective C++):
More computing sins are committed in the name of efficiency (without necessarily achieving it) than for any other single reason - including blind stupidity.
- William Wulf
We should forget about small efficiencies, say about 97% of the time: Premature optimization is the root of all evil!
- That crazy ol' wizard, Don Knuth
We follow two rules in the matter of optimization:
Rule 1.) Don't do it.
Rule 2.) (for experts only) Don't do it yet. - that is, not until you have a perfectly clear and unoptimized solution.
- M.A. Jackson
This is the paradigm by which this 20% will emerge. Why is OS X still slow? They are still "getting it right". The above quotes are testimonies by BIG NAME PROGRAMMERS that patience w.r.t. optimization is a MUST. I certainly hope all the whiners wimp out and opt for PCs instead of Macs so they can cry when our OS gets "finished" and begins kicking some real ass!

Taking the debugging code out.
& maybe some nice new procs. to go along with this @ mwny ;-)?

What? Are you sure? 5-10% seems awful low compared to what I've been reading.
If your right about the speed increase percentage, that sux...
Has anyone done benchmarks other than those of the "feels snappier", RDF variety?
Gimme the numbers
