PhoneGap Up To Speed

I recently ran across some major performance problems with a jQTouch app running in PhoneGap. Some of the symptoms included long pauses on touch events, non-responsiveness, and laggy transitions.

Brian LeRoux (Nitobi/PhoneGap), Jesse McFayden (Nitobi/PhoneGap), and David Kaneda (jQTouch) were the stars looking into this issue. Ends up Jesse found where the Accelerometer was taking a 40Hz sample rate and sending the data to a callback. The solution is to just disable Accelerometer use – either in the plist or, as I did, comment-out all the accelerometer bits. Likewise, I removed location functionality, as this app in particular doesn’t need it.
