Performance Issue

[AmrElsayed]

Hi,

I am using Keno Mobile with PhoneGap in my application, I am replicating a list view similar to the one showed in the demo.
However, scrolling through the list items takes a considerable time to render the rest of the list items.

Can you have any suggestions about the source of this performance issue?

Thanks,
Amr

Hi,

In general, heavy graphics and CSS effects of the listview content cause such slowdown. The scrolling performance also depends on the browser accelerated compositing, which can be triggered in various ways, most common one being applying 

-webkit-transform: translateZ(0) 

to the elements inside the listview items.  

All the best,
