The profile suggests that some time is spent in Baseline JIT. Maybe some improvement can be done here?

Upon further investigation, this appears to bad across browsers. While it does take some time to refresh in Firefox, it also does in Chrome and Safari and the longer you run it, the worse it gets. This seems to be a JS intensive demo and we believe there isn't much to do here.
