What Notion Ink thinks could be the reason for Android touch input lag

It could be something to do with the garbage collector

Notion Ink CEO Rohan Shravan says in the official blog that the Adam might get Honeycomb after all, but it will be some time before that happens. One of the reasons he gives is an ongoing investigation regarding the touch input lag Android has at times. This is specifically prominent when you are running memory intensive program and in the middle of it, come to the homepage. There are other areas where Android Honeycomb gives a performance lag like for example while moving icons around, or while displaying UI animations etc.

Rohan says it could be the garbage collector problem. As long as the garbage collector exists, it can take anywhere between 7ms-500ms to do its work. This is the time we might have to wait between two instructions. This could result in a skipping of as many as 10 frames per second.

Although Rohan says they are working on modifying it, there was no ETA provided for the solution.
