javascript - jQuery 1.3 vs 1.4 (Performance) -

-

jquery 1.4 released , new website shows performance charts 1.4 better, has done analysis of overall performance improvement of 1.4 vs 1.3? if not, how profile both on sites/pages, there tools?

can't wait find out how fast 1.4 compared previous version.

edit: blogger did tests , found 30% faster in ff slower (compared 1.3) in safari. hmm...

their diagrams show 1 side of story. i've been working on script involves iterating on thousands of input elements throughout dom tree , traversing parent elements. according firebug, jquery 1.4 runs 30% slower 1.3.2 on exact js , dom structure.

that's not 1.4 isn't "faster" in general though, , in 1 browser i've profiled in. think time efforts more focused on speeding areas related dynamic content creation rather dealing existing static elements.

just thought should point charts list number of function calls, not execution time. fewer function calls doesn't translate lower execution time. in situation 1.4 executes 20% fewer calls runs 30% slower.
