Great page, that is a cool utility that I'm sure I will use in the future!
You've shown the "old school" methods are clearly faster for the top
browsers (FF,IE6/7) which I think would make the change to
String.replace or String.split worthwhile. (I was able to reproduce your
results, only mine were a lot faster across the board, what CPU are you
using?)
Even though String.replace is slower in Opera I'd be in favor of it
since Opera clearly has some room for improvement with that function so
I'm guessing this may be improved in the future.
Thanks,
Colin

On 2), why can't the escapeHTML function create a div node and a text
node once one the first call and reuse it on subsequent calls? Also,
is this not a leak?
a) this is veeeery browser dependent :(
b) leak? can't see a reason why.
That's something we'd need to measure.
Let's measure. Note that I threw in two more "old school" methods
(string manipulation based).
