Stripe API is slowest to build at about 1.2s, the depth of the schemas on that spec are insane. The only way to speed things up here is to NOT wait for threads to finish before returning the model, and this creates a broken guarantee as the model won't be finished building by the time its returned to the consumer. When running tests against this - they fail randomly. depending on which thread reaches the finish first, before trying to be read.
This isn't an option, so for now, this is as fast as she will get, which is pretty good. 5ms for petstore and about 250ms for k8s.
sibling nodes with references were being destroyed when resolved. Copies are now made instead of using pointers for this specific item, as the fidelity is lost when using the resolver (the refs are resolved and there is no way to re-locate the original positon of the reference.
