Just to check, this is a build with JaegerMonkey enabled, right? I'm pretty sure we have existing bugs about this demo in its non-chrome-experiment incarnation... But in any case, looks about like this (all percentages are "under" unless they explicitly say "in"): 20% in mjit-generated code 20% Fill on the canvas 10% NewInitObject + GC 9% painting 5% SetName<0> (half is allocating slots and half is setting canvas styles) 5% InitPropOrMethod 4% stubs::CallName (mostly under NameOp getting call vars, looks like) 3% array_join 3% stubs::NewArray 3% array_sort 3% array_extra (mostly creating array objects) 2% FillRect on canvas 2% NewObject 3% finalizer thread
