A Study of Ajax Performance Issues

Tagged:  

Coach Wei has posted an interesting study of Ajax performance issues, specifically addressing the following issues:

1. Array performance on all browsers in general
2. HTML DOM performance in general
3. Calculating Computed Box Model and Style
4. FireFox: “eval”, Object Creation and “in” Operation
5. “String” Manipulation Performance on IE
6. Safari: “pop” Operation Performance

The article reviews data captured by Robert Buffone at RockStarApps and draws some interesting conclusions.

Visit Couch Wei's blog to read the full study.
