All the benchmarks seem to indicate that Angular 2 is vastly faster than the other frameworks - the Angular team has achieved O(1) change detection, which large DOM node benchmarks are remarkably consistent with in terms of Angular 2&#x27;s performance. For large numbers of repeated elements, it turns out that Angular 2&#x27;s performance is worlds away from even libraries like React. For more normal situations of smaller # of DOM nodes, Angular 2 still manages to outperform by around 3-5 times as fast - all the benchmarks I have saw was pre-web worker support though, so it may be even better with that enabled.<p>I don&#x27;t remember Ember&#x27;s performance, but React&#x27;s seems to slow down significantly in jumps at certain marks, similar to Angular 1, which seems to suggest they have some at least one place where optimization could be made. It should be noted though that Angular 2 builds on top of many rock solid principles that React introduced, and has ruthlessly optimized upon that with continuous benchmarking and careful planning.
