[Firefox] Jägermonkey: it’s in ur browser

I've tested

http://nightly.mozilla.org/js-preview.html

with my simple benchmark loop (two floating point additions per pass) and it's really better:

300M passes of loop, time in seconds:

0.88 Firefox 4b6

2.26 Firefox 3.6.6

which is approximately 2.5 times faster.

Now that particular loop executes at the same speed as ActionScript 3 (in Flash 10) with explicit typing. That's the big achievement for Mozilla.

Here's some more data from Mozilla's own testing setup:

Where JM+TM stands for "Jagermonkey + Tracemonkey". It looks to be gaining on V8 and Apple Nitro pretty fast, considering the timeline involved.

Also like the big "No." mid page.

The team seems to be pretty focused on getting to be faster than Chrome/Safari. Great idea to have a simple goal, and a simple answer to whether they have achieved it or not.

Looking at their v8 bench speedup: from 0.7 ms to around 0.3 ms we get again 2.3, comparable with the simple loop measurement. But interestingly enough, Google's V8 gets its speed in a very different way, as my mentioned benchmark loop performs much worse in Chrome: 3.9 sec on Chrome 6.0.472, thats 4.4 times slower than ActionScript or Firefox Beta 4.
