JavaScript Object Oriented Libraries Benchmark

JavaScript performance comparison

Revision 79 of this test case created by André Cruz

Info

MooTools and Ext Core are removed because they add extra information into native classes. They slow down other libraries.

Please note that JSFace inheritance model does not play well with the native instanceof. Thats also why it is faster in firefox than any other library.

TODO: - Add YUI
