It’s more a measure of rendering performance between a single Bitmap vs. thousands of overlapping objects rather than the tweening engines themselves. When tweening massive amounts of overlapping DisplayObjects that all share the same parent, it’s a great technique, but keep in mind that there are trade offs and limitations that may not be acceptable in your project. The tests on the Tweensy site are using an old/stale version of TweenMax that was definitely slower than the newest release (http://www.TweenMax.com). Don’t get me wrong - Shane has done a great job of building a fast, capable engine. I’d encourage everyone to do their own real-world tests, though. http://blog.greensock.com/tweening-speed-test/ seems to be a more apples-to-apples comparison and [at least on my machine] TweenLite is indeed fastest. Gortex, a competent, full-featured tweening engine takes a heck of a lot more than a day to build. Look at how long it took a brilliant guy like Grant Skinner or any of the other authors. Sure, it's not hard to build an ENTER_FRAME loop or timer that updates values, but a full-fledged engine that manages overwriting, sequencing, optimizes speed, etc. is much more involved. There are many pitfalls to avoid. If you prefer rolling your own, though, more power to you.

Have you checked out the demo for Tweensy? It looks like Tweensy is pretty fast. http://www.flashdynamix.com/examples/Tweensy/0.2/SuperRenderTweenTest.html You marked TweenLite as the one with the best speed.

The idea is that we want standardized tweening in some ways and this helps. Before AS3 for instance everyone implemented these as their own, and some do in AS3 as well. As a programmer you should be able to, as an architect you want others to standardize on formats so you can take it to the next level and build platforms on that. Standards are what make platforms great and able to innovate on top of, exhibit a: the internet. Gortex, I agree but at this point we have enough custom tween engines.

The obsession with tweening is an embarrassment to the entire flash community. If you can’t write your own tweening engine in a day you should be working at mcdonalds.

Personally, I like the innovative features Grant's gTween is offering. While it is still in its beta state, it comes equipped with some mighty sweet features.

I second PeZ's suggestion to take a look at Tweensy ( it's got some really great demos, and Shane's done a great job introducing a new Tween engine into an already robust market ).
