Hi,

I just regonized, that the scroll performance is very bad since A4. Just check the demo page menu on a iPhone 3G on
http://jquerymobile.com/demos/1.0a4.1/
and
http://jquerymobile.com/demos/1.0a3/

The scrolling via vertical swipe gesture is very bumpy since A4.

Regards
Timo

Hi jblas,

thanks for your fast investigation.

Unfortunately, the scroll performance is still significantly worse on
http://jquerymobile.com/demos/test
than on
http://jquerymobile.com/demos/1.0a3/

Hi,

I'm having the same problem. In my ipod touch 2º generation the scroll performance since alpha 4 is significantly worse, even with the fix applied. On iphone 4, this issue is not noticeable.

Same here, even on iPhone 4 I notice is a slight slowness. I can "fix" the issue by removing the vmouse code altogether.

Landed more optimizations that should make scrolling much more responsive.

I confirm this optimization fixed the issue on iPhone 3G. GG
