Jack Slocum - creator of my favorite JavaScript library¹ Ext JS - ran some tests using SlickSpeed from the MooTools developers with the latest development release of Ext JS, 1.1 RC1.

I ran a few additional tests with the following configurations:

• Firefox 2.0.0.4, Safari 3.0.22.522.12: OS X 10.4.10 on a Mac Book Pro 2.33GHz Core 2 Duo, 3GB RAM.
• Safari 3.0.2.522.13.1: IE 6 on XP, dual-core Opteron 175, 4GB RAM.
• IE 7: XP, VMWare Workstation 6.0.0.45731², 1 CPU from the dual-core Opteron 175, 512MB RAM

Library	IE 7	Firefox 2	Safari 3 (Mac)	Safari 3 (Win)	IE 6
Ext	183 ms	314 ms	116 ms	64 ms	461 ms
jQuery	362 ms	442 ms	197 ms	160 ms	861 ms
Dojo	427 ms	363 ms	188 ms	191 ms	780 ms
MooTools	838 ms (4 err)	194 ms (2 err)	158 ms (2 err)	128 ms (2 err)	1333 ms
Prototype	1097 ms	198 ms (2 err)	158 ms	88 ms	1674 ms

I didn't count zero results as errors, in retrospect I probably should have.

1. "Library" doesn't really do it justice, it's a tremendous collection of "JavaScript, Ajax and UI components" [back]
2. Not really fair, I know, but it still outperformed IE 6 [back]
