At 2000 fish I get about 23fps in FF but get 60FPS in Chrome. 81% of the time is spent under EnterMethodJIT It looks a there's a bunch of heap churn from things like JSObect::allocSlots() also 3.6% of the time is is in js::mjit::stubs::UncachedCallHelper()
Can you post the profiles?
(In reply to comment #1) > Can you post the profiles? Sure (http://people.mozilla.com/~jmuizelaar/fishbowl/Instruments2.trace.gz) but it should be easy enough to just profile.
The GC pauses are only 4msec :)
Yeah probably L2 cache misses on allocation and maybe the frequent mallocs.
Sure the object growth seems to be a problem. Maybe bug 547327 would help? I never get 60FPS with Chrome. It's only 22 for the release and 40 for the canary version. FF nightly is also 22 FPS for me.
I get 60 fps with 2000 fish on OS X, with/without IonMonkey. Please reopen if you still see this.
