Last night I decided to try the performance of the new TraceMonkey feature. TraceMonkey is an improvement to Mozilla's SpiderMonkey JavaScript engine, which enables JIT optimizations to SpiderMonkey, which means that the engine optimizes the parts of your JavaScript code which run repeatedly (e.g., loops). For more information on TraceMonkey, check out Brendan's announcement of TraceMonkey. I gave Mozilla's Dromaeo, Webkit's SunSpider, and Google's V8 Benchmark Suite a try, and the results follow.
