Just been going through some of my current work and seeing what improvements come with jQuery 1.1.3. Unfortunately it looks like there's a bit of a regression in terms of speed for Firefox (2.0.0.4).
So far I've only looked at the speed decrease when selecting 'input' elements, so it may be isolated to them or something general. You'll need Firebug on Firefox. Firebug lite is included though. Here's a page with using 1.1.2: http://krudd.net/jquery113speed/jquery_elementtest_112.html Result: setup: 781ms Here's the same page using 1.1.3: http://krudd.net/jquery113speed/jquery_elementtest_113.html Result: setup: 1937ms And for kicks I looked at using "straight" DOM methods to select the 'inputs' (getElementsByTagName) and 1.1.3: http://krudd.net/jquery113speed/jquery_elementtest_113_dom.html Result: setup: 531ms I haven't had time to dig through the 1.1.3 source to see where the slowdown could be occurring. Anyone have any ideas? Under IE there is a similar, though markedly smaller, slow down between 1.1.2 and 1.1.3. Karl Rudd
