V8, the JavaScript engine inside Google Chrome has added a new competitor to the battle for faster JavaScript. Today, Brendan Eich, CTO at Mozilla, posted benchmarks comparing the latest TraceMonkey release in Firefox with V8 in Google Chrome.

The aggregate results are good for TraceMonkey, showing it around 20 per cent faster than V8. In individual benchmarks where recursion is involved, V8 is "cleaning our clock" according to Eich. He points out TraceMonkey's developers already have a plan to address this issue by tracing recursion in JavaScript code.

Eich welcomes the competition from V8 saying it is "great work, very well-engineered, with room to speed up too" and calls the Chrome multiprocess architecture "righteous". Eich also says that TraceMonkey has a lot more room for optimisation concluding "If we are right, we'll find out over the next weeks and months, and so will you all."
