tl;dr getTime in windows only updates every 15 ms, so if your performance benchmark cares about that kind of period then it isn't going to give very good results.

Every time I hear about performance testing in JS it seems to be that it doesn't really handle IE very well for whatever reason it is today. It looks like this bug would have made IE look like it performs better than it actually does though.
