Deserializing JSON from custom connector is super slow

I have a custom connector to a web API which is returning roughly 60k of json data that really just a matrix of numbers about 30 x 100 in shape.


My issue is that PowerApps is taking ~1500ms to deserialize this into a collection which is an inordinate amount of time given the entire round trip is about 300ms up to that point.


So I dont really have a question as such, just wondering if anyone is familiar with the mechanics behind the deserializer being used and how I can boost its performance. maybe the data can be organized better for example.

How is it that you are deserializing your JSON?  PowerApps does not have the capability to deserialize JSON, so perhaps whatever you have implemented to deserialize is the fault?

This is serialization that occurs coming back from a custom connector using a schema
