3.2.1 about twice slower than 2.3.0 ?
I've recently upgraded an ext2 app to ext3 and well, it felt the app went, mmm slower.
So I did a quick profiling in firebug and to my surprised, it looked like the numbers had roughly doubled, kinda everywhere in the framework. I was a bit confused, and today I did the same exercise with some ext examples.
It's surely nothing scientific, but am I wrong or the performence of the framework had drasticly decreased ?

Unfortunately, the changes to the layout system sometimes made Ext applications a lot slower.
Performance is a big concern for the developers and there have already been several changes since Ext 3.0.0 to speed things up.
For Ext 4 a complete overhaul of the layout system is planned to again make it as fast or faster than Ext 2.

+1 to this - we are stuck with v2.3 and cannot upgrade until the performance is at least on par with what our user's currently get.
I thought v3.1.1 was supposed to address the performance issues? And all the work done by @Meroy?
Some more numbers:
3.2.1: 302.521, 13687 calls
2.3.0: 218.939, 7783 calls

does v2.3 contains bugs that where fixed in v3.x ?
in other words, when a major version stops to be supported ?
