I’ve just updated my app to Ember 1.8 and Ember Data beta 11 (from Ember 1.7 and Ember Data beta 9) and I’ve noticed a 10+% slowdown on calls to
store.pushPayload (with 5000+ items). The 10% difference is extremely noticeable because the call is already very slow on Android (my target platform).
Is this a known issue? Is there anywhere specific I should start looking to optimise this? Or a way to debug exactly what’s taking the time?
