How much overhead is using emulated stack in GWT?

I'm considering 开发者_如何学Pythonusing GWT's emulated stack in web-mode and I wanted to hear, based on people's experience how much performance overhead it added?

From what I read in the above link all of the overhead is the couple of arrays and their handling as a stack which is very reasonable in my eyes.

I just want to make sure there's no cat in the bag.

Also, a reasonable increase in the size of the js files is ok by me as my users connect to very long sessions and can wait the few additional ms.

Thanks,

Ittai

I don't have any data on execution speed, but Googler David Chandler stated in this discussion that removing stack info can reduce compiled JS size by as much as 15%.
