| _For additional improvements when fully using the ember-strict-resolver monkey patching the registry to no longer cache and simply returning the values passed like the following can be produce extra performance._ | ||
|
|
||
| ```js | ||
| // disable the normalization cache as we no longer normalize, the cache has become a bottle neck. | ||
| Ember.Registry.prototype.normalize = function (i) { | ||
| return i; | ||

There was a problem hiding this comment.
However, I have a broader comment, which is: if we think this is worth doing, we should build a public API for it. It's one thing to do this as an experiment in our app (a successful one, I might add!) but we should not recommend others do it until there is a public API, or else we're setting people up for pain.

Summary
Originally from https://github.com/stefanpenner/ember-strict-resolver we have been using this in production for a few years! It is faster and less prone to errors as it doesn't allow configuration.
It would be great to support this as a first class resolver.
Details
When debugging how often we call into the resolver to access values from the registry, on an initial page load of linkedin feed we access the registry ~11,800 times.
When running linked.com feed using the ember-strict resolver we see in the experiment over ~300ms faster The differences are:
boot phase estimated difference -188ms [-195ms to -181ms]
transition phase estimated difference -42ms [-57ms to -27ms]
render phase estimated difference -23ms [-37ms to -9ms]
