Rendering performance


#1

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.


#2

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


#3

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.


#4

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


#5

Any tips on converting each helpers to collections views?
