From the ‘I want TachyonMonkey next’ files:
The latest entrant is yet another ‘monkey’ from Mozilla. This time it’s called IonMonkey and it follows in the footsteps of JagerMonkey, TraceMonkey and their granddaddy SpiderMonkey (which I first wrote about back in 2007).
In a blog post, Mozilla engineer David Anderson confirms my suspicion noting that,” IonMonkey is targeted at long-running applications (we fall back to JägerMonkey for very short ones).”
Reality is that many modern web apps are long running apps, so my I suspect my concern is a non-issue too.
The performance improvement ranges from 7 to 26 percent over Firefox 17 depending on the benchmark.
Firefox 18 is still a few months out from being generally available, so users will need to wait to benefit from the speed boost. Firefox 18 is currently in the Nightly release branch and is scheduled to enter beta on November 20th.
