Hello, I have a problem with Sortable performance.
If I use Sortable my browser uses a lot of cpu :
- 25 to 40% on my core 2 duo 1.8Ghz
- 50% of cpu usage on P4 3Ghz
(Amount of CPU is not exactly the same, depending on the browser I
use, but it is high in all cases)
This online demo is enough to reproduce it :
http://dev.jquery.com/view/tags/ui/latest/demos/functional/#ui.sortable
I've tested it on :
IE6 ,IE7,FF2,FF3, Opera 9.5, Safari 3, Chrome, all on Windows XP SP3,
and Opera on Windows Vista
I've tested JQuery UI version : 1.5.2 , 1.6pre, and Latest SVN
version.
For Dual Core processor, the other core keeps the system available.
But on single core processor, there can be some lags. (and heavy lag
if you test with more Sortables than in the demo)
With incoming netbooks, I think that small cpu will be there for a
long time.
I want to develop a website for everyone, and if I use a Sortable I
will lose some users.
Have you any idea to reduce it ?
