Oddly enough, the prototype version looks quite a bit choppier in FireFox than the jQuery version does for me. The jQuery one's not really choppy at all.
This is FF 1.5.0.7 on WinXP on a thinkpad. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of herchenx Sent: Friday, September 29, 2006 9:41 AM To: [email protected] Subject: Re: [jQuery] Multiple Simultaneous Animations slow down Firefox Here is an example: http://www.daharsh.net/jsTest/jQueryVSScriptaculousSilultaneousAnimation s My Example There are 2 links, one to another example using jQuery and slideUp() (which does not illustrate the problem quite as clearly, but you can still see it) - and another example using Scriptaculous and Prototype (which works almost exactly the same in IE and FF, although the performance in IE is not as nice as jQuery) Obviously jQuery wins for filesize, and in IE it looks a lot better, but in FF the performance is awful.
