Jquery mobile framework in android OS

Why jquery mobile framewor开发者_运维技巧k is slow performance in android2.2 OS

---

Jose - you can't get any sense of the speed on an emulator - there is absolutely no comparison. jQuery mobile is one framework I've been evaluating also - on an iPhone 4 it is 'not bad' but still sluggish overall and on Android 2.1 it is so slow as to be nearly unusable. I'm concerned that the reuse of jQuery as a whole in the mobile side is just too big and too slow. On a side note - Sencha Touch doesn't perform much better on Android. On iOS it is better than jQueryMobile's alpha release - that may change.

I have experienced the same issue: jquery mobile is not very responsive even on my Samsung Captivate (a fast, new model from mid-2010). My best guess is that it is only an alpha release, and that it will get faster once the architecture and feature set decisions are complete and it moves towards a 1.0 release.

JQuery Mobile is currently in Beta 3 and will soon release version 1.0. With that have come significant improvements in speed and reduced user perceived latency (UPL). My latest mobile app runs on Android 2.2.1 and I'm using JQuery Mobile Beta 3. It runs great! I'm running my app on the actual device and not in a simulator. Also, during your development, when it comes to application optimization, you might want to check out YSlow and Page Speed as plugin tools for Firefox/Firebug to determine the root cause of any latency issues.

First thing is, 99,9% of available mobile frameworks are slow. This is due to:

1. Smartphones are still to slow, if you take a look at any desktop/mobile JavaScript benchmark you will see that desktop browsers always overpower mobile browsers bye far.
2. Mobile frameworks are usually slow.
