101 on jQuery Selector Performance

Last week I got to analyze a web page that spent 4.8 seconds in the onLoad event handler of a custom script file. It turned out that 2.8 seconds were consumed by applying a dynamic menu library (will blog about this one separately). The remaining 2 seconds were spent in jQuery selectors. The analysis showed that most of the selectors didn’t return any object and those that returned objects can be improved by using different selectors.
