I have read some articles that said ng-repeat would led to poor performance if there is over 2000 items, because there are too many two way binding to watch. I am new to ang
what ever is generated by ng-model will be having a watcher on data(model) which reduces the page performance if it crosses 200 watchers.
Refer this for ONE WAY BINDING http://blog.scalyr.com/2013/10/31/angularjs-1200ms-to-35ms/ but make sure you use it properly
Hope it helps!!!
