Now, here comes KTween's turn:

Running on my MacBook Pro, Mac OS X 10.6.3, Core 2 Duo 2.26GHz, Flash Player 10.1 Release Candidate, Firefox plug-in, the bench shows the KTween is a teeny bit faster than the Eaze. However, I could say it's still in the range of error.

The bench runs with the engines below:
KTween - Version 1.0.1 Revision 79
BetweenAS3 - Revision 3765.
GTween - Version 2.01 (2009/12/11)
tweener - Revision 424
TweenNano – Version 1.03 (2010/04/03)
eaze-tween - Revision 74
I guess it'd be rare that a case tweens 4,000 particles though. :-)

* Note that the benchmark result is depend on machine, OS, flash player version and revision etc. The BetweenAS3 becomes the fastest engine in the six above in a case for instance.
