Ember.js Performance
summary
Shows concrete wins: Bluebird makes promises an order of magnitude faster by allocating less and aligning with V8; profiling and Crankshaft explain why. Identifies costly patterns—excess allocations, two-way bindings, singleton controllers, meta/listener bloat—and proposes fixes: do less work, actions up bindings down, change super/init defaults, and limit reopen to pre-instantiation. Early spikes against V8 and prototype profiler runs report substantial speedups but not yet production-ready. Warns that microbenchmarks lie and advocates targeted, measured changes.
