improving performance using javascript

Hi folks,

In general, there is no way to improve the performance of a report through JavaScript. JavaScript only takes effect after the report has run.

Poor report performance can usually be traced to data issues, such as poorly built queries or the misuse of indexes. I've also seen poor performance from too many objects on a page. Charts for instance, every hot spot is at least a kb of HTML. Too many hotspots and your browser will freeze.

If you expand on what the issue is then we may be able to advise you further.
