Details

A benchmark of bananabread in the shell is available as follows:

1. git clone git@github.com:kripken/misc-js-benchmarks.git
2. cd banana/shell
3. edit runme.sh so js points to your spidermonkey shell
4. run ./runme.sh

Running it with --no-ion I get 8.74ms, while running it normally with IonMonkey I get 9.61ms per frame, almost 10% slower.

(With --ion-limit-script-size=off, it is a few percent faster than normal ion. But there are noticeable large pauses and the variance goes up.)
