Dunno if regression jerk or what , but we got nice win on Octane and v8 (which look exactly same to me though , for FF and Chrome)

Maybe coz of landing of many IonMonkey patches lately? : viewtopic.php?f=23&t=2645951

First they are adding Exact Rooting mechanism then they will add Generational GC on it and then remove its overhead. They are progressing good so lets see.

I think GGC will come in 2013. IMO, These patches landing means that they're relatively close.

Exact Rooting still have lots of Bugs opened and progress has been slow. We need that before moving on to GGC....

Something broken in the 64bit charts, as they haven't been updated for about a week.

Same for ARM, but that's not overly unusual for that machine.

Nice to see that Ion allowed Firefox to nearly catch up to Chrome in such a short amount of time.

The best part about the new Baseline would be to get rid of ( JM + TI ). Hopefully some Codesize and memory reduction would be a side effect as well.
Along with GGC the JS in Firefox has finally catched up in Chrome.
