Rendering performance


On one of my pages I’m rendering a longish list in a table and it is getting pretty darn slow.

Is there some best practices to analyze performance and improve the speed.


Have you checked out the Render tab in the Ember Inspector? I’ve used it for this kind of stuff before…


Run your test in production mode, you should see a significant gain.

ember s --environment=production

Also, replace your each helpers (I’m guessing there are two since tables are two-dimensional) with collection views. You’ll get noticeable perf. gains with those two suggestions.


Yes I tried using the results on the render tab but it lists tons of kernel calls I’m not familiar with.


Any tips on converting each helpers to collections views?
