Ajax lib comparison

From: http://www.ibm.com/developerworks/cn/web/wa-aj-advjquery/

 

Conclusion 1: the performance of mootools, jquery, and dojo is different.

According to the performance classification, these libraries can be divided into two groups, regardless of the browser (FF, ie, Chrome ). Mootools, dojo, and jquery usually belong to one group, while prototype and Yui belong to another group. The former group is much faster than the latter group.

 

The main reason for the difference in Javascript speed is that each browser uses its own JavaScript Engine. Javascript runs in these browsers for a long time. The jquery selection method runs 10 times slower on IE6 than on chrome.

 

Conclusion 2: Prototype And Yui have slow performance.

 

Conclusion 3: the effect of the browser on the performance is 9 times that of the Javascript library.You can discuss which JavaScript library is the fastest in a specific situation, but the final impact is very small! For performance, the browser has a much greater impact than the library itself.
