(Originally taken from the Skylight "almost daily" emails, written by Tom Dale)

It was a very busy week. We spent the first three days of the week digging deep into Glimmer performance. As we've been scrambling to bring the benefits of this brand new approach to rendering to the many existing Ember apps, we inadvertently added some performance regressions while adding backwards compatibility features.

We spent many hours staring at the profiler in Chrome, trying to figure out how to optimize Glimmer's rendering performance at both the micro and macro level.

One of the biggest improvements was minimizing the number of DOM manipulations for certain cases of re-rendering an each helper in Ember. You can see more of the specific details in the commit here: https://github.com/tildeio/htmlbars/commit/64be35ef03953d80cfe4434446a01dd483bba7b0

This definitely involved busting out some rusty Computer Science skills, but it's always fun to explore algorithms and

A possible usage for the controllers property ...

App.AutoSuggestController = Ember.Controller.extend({
