Performance

13

Ensure.js

  http://ensure.codeplex.com   Loads JS/HTML/CSS dynamically.   Really, really useful.

14

Write better CSS

  Super-fancy CSS3 operations are also super-expensive.   This:

div.header span   Is slower than this:

div span.header

15

Other Tips

  Don’t use big images!   Follow JavaScript/Sencha best practices.
