[jQuery] Re: 1.3.1 is over 10x slower than 1.2.6
I know you've already said you can't release the code of your actual project, but would it be possible for you to construct some test cases that demonstrate the speed penalty that you are suffering in 1.3 compared to 1.2? It would be interesting to see what circumstances are triggering this and whether or not 1.3 really is slower under some circumstances. I know the jQuery team prefer optimizing for the most common cases, it is possible that in doing so the library may become less optimized in terms of the less commonly used functionality.

[jQuery] Re: 1.3.1 is over 10x slower than 1.2.6
I had the same problem, I still do actually and the only workaround was to turn off firebug. I also noticed that it wasn't so much the injected html that was causing the issue, rather it was binded events and animations (most likely). John, if you want I'll try and test this and determine the causes On Jan 23, 7:58 am, Loren lorenw...@gmail.com wrote: Thanks to John and the jQuery team, the problem was identified and found.

[jQuery] Re: 1.3.1 is over 10x slower than 1.2.6
jQuery is used in some very high profile places, by countless people/ websites all over the world ... and yet the jQuery team takes the time to provide this kind of support. The really great thing is that this is not abnormal. With regards to jQuery (and the team/community), there is nothing special about what just happened. The decision to adopt a framework/library/etc should never be based solely on a feature set (I've gotten into trouble making this kind of decision before). This thread is a great illustration of the other factors to take into consideration before making a decision. This is one of the reasons why it is so easy to choose jQuery when, in a project, the opportunity presents itself!!

[jQuery] Re: 1.3.1 is over 10x slower than 1.2.6
Yes, I expect the new event triggering logic to be the cause of the slowdown. In two other areas I had manually called trigger() during a mouseover event. Whenever my mouse passed over that element, my machine froze - cpu pegged at 100% for several seconds. This was also while I was running that old FF profile. After reading the upgrade docs, I added a stopPropagation() in my event handler, and that solved the problem. My guess is that this is a similar issue with my initialization. Over the weekend I will assemble a test case simulating the things our app does on startup. I'll try to determine the root cause and post to the list, along with the test case. -Loren

Hi John, Thank you for the reply. Firebug is set up for auto updates - am running version 1.3.0 of firebug. We're a startup building a consumer app, and our product isn't publicly available. Our investor wouldn't want us to put our app on a public server at this time. I know you've put a lot of effort into 1.3, and don't like to see reports like this, so I will set up a temporary portal for you, and send a link to your personal email so you can see what's happening. I'm committed to keeping jQuery the best it can be. Our product is built on top of it, and if it fails, we fail.

Thanks to John and the jQuery team, the problem was identified and found. It turns out I had a bad FireFox profile. For some reason, still unknown to everyone, if you see tremendous speed problems (in and out of firebug), try creating a new FireFox profile (firefox.exe -p), and use that one instead. You'll have to add back your bookmarks, options, and add-ons, but it's what fixed my 10x speed problem. v1.3 is still somewhat slower than v1.2, but they're both well within an acceptable margin.
