How are you serializing the pydantic objects this fast?

[AbbasCiatek]

I'm very puzzled by the fact that when I try to serialize the same pydantic object from a dict, its making 2-3 times as much time as me getting the form from the db directly which is super weird

Time to get form from cache: 2.071380615234375 ms
Time to json load form: 4.654407501220703 ms
Time to instantiate form: 74.60212707519531 ms
Time to get form from db: 24.610519409179688 ms
others: 1.863718032836914 ms
Total time to get form: 107.85889625549316 ms

even when trying to duplicate your setup:
form = cast(AbstractFormDocument, parse_obj(AbstractFormDocument, dict_cache))

are you doing something special ?
