Correct. One minute ago when I ran the tests in ie55, results were:
Built in methods: 78713ms
Hyper String: 301ms
StringBuffer: 100ms
I wouldn't rely on those numbers though, because my system seems to be
running low on virtual memory. Especially the built in methods test is most
likely to suffer from the memory shortage.
