REST framework
This article(https://hakibenita.com/django-rest-framework-slow) suggests that ModelSerializers are slower than general serializers.
According to this post's(https://www.reddit.com/r/django/comments/sesi0s/modelserializer_or_serializer_which_one_is_better/) discussion there is no significant difference 😦 and normal serializers performance is unstable and sometimes performs worse.
I wonder if anyone else tested it.
