Ever more impressive. Well done you lot, you make us proud! George

Looks like another good release, yet more performance improvements and a few useful new features! Regarding speed testing, maybe it is worth mentioning the PC specification of the machine that performs these tests? For example, mine (Core Duo 1.6Ghz) .extend() 1.2.3 - 63 1.2.6 - 46 .map() 1.2.3 - 2268 1.2.6 - 203 Still a performance improvement, but not as great as the test machine - i.e. the faster the client PC processor, the better the performance improvement (I don't think RAM will have much of an impact as the CPU is doing the work). Perhaps the tests should be done on different spec machines, more so the low end ones (Celeron, Sempron and Intel Atom)? -Sam On Jun 3, 6:46 pm, Rey Bango [EMAIL PROTECTED] wrote: jQuery v1.2.6 is now official and release notes have been posted:http://docs.jquery.com/Release:jQuery_1.2.6 The biggest changes are improvements in performance, especially event handling, which is now 103% faster.

Still a performance improvement, but not as great as the test machine - i.e. the faster the client PC processor, the better the performance improvement (I don't think RAM will have much of an impact as the CPU is doing the work). How so? Your .extend() improved by 37% and your .map() improved by 1017%. Those are well within the realm of what we posted. The speed of the processor shouldn't affect the degree of relative improvement. --John

I suppose a few % points off isn't that much of a difference and in some cases were even better. But I expect mine isn't too far off the test machine. Think I got my maths the wrong way round: ((1.2.3 time - 1.2.6 time) / 1.2.3 time) * 100 e.g. for .extend(): ((63 - 46) / 63) * 100 (17 / 63) * 100 = 27% improvement Maybe that's why I made that conclusion. What I am interested in is how the lower spec PC's performed (non-dual core, entry level machines), to see if multi-core processors actually make much of a difference (since many users of website using jQuery will have these type of PC's). .map() is the major improvement in this release as a few milliseconds off a fast method like .extend() won't mean as much (although if it is called a lot it adds up to more savings). .offset() is still a bottleneck (browser quirks stop any major improvements), but caching values and restricting how often it is called helps mitigate that (I think Flash is still far smoother when it comes to mouse tracking and animation - which can be very slow over a Citrix connection). Animation performance is not something that can be tested with unit tests (still need a human to do that). How does it compare with other libraries now? -Sam On Jun 4, 1:21 pm, John Resig [EMAIL PROTECTED] wrote: Still a performance improvement, but not as great as the test machine - i.e. the faster the client PC processor, the better the performance improvement (I don't think RAM will have much of an impact as the CPU is doing the work).

.extend() was used extensively in the event handling code, hence the need for improvement. How does it compare with other libraries now? How does what compare? No other library is making the optimizations we are - or even examining how to perform faster operations here. --John
[jQuery] Re: jQuery v1.2.6 is now Officially Released and Release Notes are Available
Mainly CSS selector tests, but perhaps also methods that may be common among libraries (like map, extend), but that may be more difficult. There is this one, but it uses old libraries (not just jQuery): http://dev.jquery.com/~john/slick/ -Sam On Jun 4, 3:52 pm, John Resig [EMAIL PROTECTED] wrote: .extend() was used extensively in the event handling code, hence the need for improvement.

Sure, we'll take credit for that :-) --John On Wed, Jun 4, 2008 at 12:28 PM, Josh Nathanson [EMAIL PROTECTED] wrote: Great job on this release guys. I also noticed when developing a plugin that it seems the memory management in IE6 is greatly improved. I accidentally was using 1.2.1 while trying to cut memory leaks in IE6, and when I switched to 1.2.6 the memory leaks on IE6 were gone. I'm not sure if it was some combination of my code and jQuery...am I imagining this, or is this also something that was worked on, or perhaps a by-product of other optimizations? -- Josh

This looks fantastic. Thanks to everyone on the team for their continued hard work.
