TraceMonkey vs SquirrelFish

With the announcement of TraceMonkey, we saw that SpiderMonkey got a huge improvement. However, in previous benchmarks, SpiderMonkey was still slower than SquirrelFish. So, how does Trace Monkey compare versus SquirrelFish:

Overall, if you aggregate the time for each test, TraceMonkey is about 15% faster. If you do the aggregate speedup, which is the speedup for each test divided by the number of tests, it is about 2.4 x faster. Sometimes TraceMonkey is slower, but give them more than 60 days to hash it out, and I'm sure it'll get faster.


Notes: SquirrelFish and TraceMonkey were with release builds. Tests run on a MacBook Pro 2.4 ghz, 4 gigs of ram, OS X Leopard 10.5.4. TraceMonkey was just pulled about an hour ago. SquirrelFish was last nights SVN.
