We'll be posting some policy modifications on the forums soon which should address some of this. I'm hoping to have everyone on the forums bang on it soon...
Mario (and anyone else interested)
See what the latest code just committed by Jamie performs.
While we're at it, can we look at http://www.extjs.com/forum/showthread.php?t=82666 ?
onRender currently renders into a temporarily created DIV, and then the first child of that is moved into its place in the container. That's a strange thing to do, inefficient, and also means that you can only create child Components from elements which can be inside a DIV.
It seems that the render performance of the beta release 3.1.1 is still far from the 2.3 performance. If you compare my app here with IE8 you'll see that 2.3 is much faster then 3.1.1 is too slow to accept:
Will this be improved or am I doing something wrong in my design?
take a look at:
work is in progress for 3.1.1.
Yes, they say 3.1.1 will address it but I'm not sure if the beta 3.1.1-release already contains all the speed improvements. I hope not because because the current beta release still isn't fast enough for IE.
they are not done yet (see postings at the end of the topic).
