Есть ли преимущество / недостаток, чтобы открыть разные порты TCP для каждого клиента?

Question

Я строю промежуточный сервер.У меня 5 (или 6) клиентов (разные компьютеры / IP-адреса), и у каждого клиента может быть до 6 подключений -> до 36 подключений к серверу.

Лучше использовать только 1 порт для всех(например, 9000) или один отдельный порт для каждого клиента (например, 9000-9005)?

Я пишу мне простой тестовый сервер (см. Код).Это сработало, как и ожидалось, но, возможно, есть место для оптимизации.

Спасибо
