maybe someone here will find them useful...

a 3 part series from a microsoft blog
Part 1: http://blogs.msdn.com/ie/archive/2006/08/28/728654.aspx

Part 2: http://blogs.msdn.com/ie/archive/2006/11/16/ie-javascript-performance-recommendations-part-2-javascript-code-inefficiencies.aspx
(note that String concats in FF are faster the "normal" way, so the Array.join should be used with IEs only)

Part 3: http://blogs.msdn.com/ie/archive/2007/01/04/ie-jscript-performance-recommendations-part-3-javascript-code-inefficiencies.aspx

and a nice guide from opera:
