🚀 New issue to wemake-services/django-modern-rest by @sobolevn
📝 Improve the performance of `_run_checks` and `_run_async_checks` (#1454)


Currently we have two functions with logic on how to run endpoint checks:

django-modern-rest/dmr/endpoint.py

Lines 417 to 425 in 405ba9b

and then we check inside each call if this call was even needed:

django-modern-rest/dmr/endpoint.py

Lines 427 to 432 in 405ba9b

CALL is not a cheap operation in Python, so I propose a different design.
We should check if the call is needed before the call itself. And only call parts that are actually required.

This is especially important for the async code:

django-modern-rest/dmr/endpoint.py

Lines 460 to 471 in 405ba9b

Where we are awaiting 4 indeprendent coroutines.
We should not, if possible.
