On my machine:

Chromium 10.0.604.0 (without Crankshaft): http://krakenbenchmark.mozilla.org/kraken-1.0/results.html?%...

Firefox/4.0b8pre from 20101208: http://krakenbenchmark.mozilla.org/kraken-1.0/results.html?%...

Overall, Firefox is 2.08x faster.

Ubuntu 10.10 x86_64, on a Core 2 Duo 2.4GHz

Comparing these with your results, it sounds like the JS performance war just got interesting again.

Huh, that's strange Firefox nightly here is slower than Crankshaft:

I did mention my Chrome test was without Crankshaft - I'm using x86_64, and Crankshaft isn't available for that platform yet.

Doing the comparison thing, apparently TraceMonkey is ~1.2x slower than Crankshaft on your machine. Things are hotting up indeed!

Chrome with Crankshaft (which is currently only for 32-bit architecture) is faster on Kraken than Firefox nightly.
