[PERF] Class Fields Use Optimization & Made OrderedSet Faster (Again) #7454

runspired · 2021-04-10T00:58:01Z

Evaluating some of our current perf-based decisions to see if they still ring true.

This started off to see if we can clean up some of our patterns, what I found was inconclusive (which means maybe?) but in the process I also found that using declare for class fields that are initialized in the constructor is a nice boost to asset size trimming and also discovered that we were still importing all of Ember to grab GUID_KEY in InternalModel which was no longer used. The latter reminded me that OrderedSet usage was probably de-optimized when we moved to RecordData and sure enough we get a ~4.6% win making sure the set is keyed efficiently again. I also found sadness, but that will hopefully get cleaned up soon.

Findings:

moving type only field declarations to use declare has no evident perf impact but significantly improves build size.
moving some props from [[DECLARE]] to [[SET]] semantics had no evident perf impact, though this may be due to our babel config (need to investigate)
moving 1 prop in a hot path from lazy getter to eager initializer of an array did not have any evident perf impact
I discovered we could remove GUID_FOR usage entirely on InternalModel. It was only there for our use of OrderedSet
speaking of which RecordData needed GUID_FOR, but I went a step further and ported OrderedSet in and tailored it to use clientId for now and eliminated our need for guidFor and GUID_FOR. This better prepares us for refactoring to identifiers anyway, plus it's actually a good sized win for bundle size.
typing OrderedSet better revealed a few issues in Relationship.ts which have now been cleaned up

Perf Win

This is purely from having OrderedSet not need to call guidFor on recordData which does not have a GUID_KEY already.
