Would be super awesome if you could share what you find! Having the same issues here - and I have a real time accepting that stuff becomes slow when you wanna return over 1k records. Sometimes way less for advanced things. Read: nested objects. But that slow? Come on.

I also use nestjs and there it seems updates to how to resolve a field has made it tons faster l, purely looking at the trace.

And I know that it won't be as fast as regular old json due to the checking but that slow? Must be something someone can do :)
