Two orders of magnitude. I just checked, and on my laptop http://web.mit.edu/bzbarsky/www/mandelbrot-clean.html (the first JS thing I wrote where performance of the language itself seriously mattered) runs in about 30-60ms in modern browsers. On the same hardware, it runs in about 2200ms in Firefox 3, which is the last pre-JIT version of Firefox. Other benchmarks I've tried show similar improvements results. And that's only going back to 2008; the interpreter was a good bit slower another 8 years before that.
