I see a lot of notes about EFS's performance in the comments. I figured it's at least worth noting, for anyone considering using ECS with EFS, that just last week EFS had its read throughput on its general purpose tier increased by 400%.

That probably won't solve all EFS performance issues, but it's a pretty big boost and a nice announcement to come alongside ECS support.
