In the world of MMO gaming, managing a high demand for connections is a challenge. To ensure a smooth gaming experience, layered architectures, dedicated servers, and clever strategies are used. However, simply creating one thread per connection can lead to resource inefficiencies and increased latency. Instead, grouping multiple connections into the same thread can be more efficient. Additionally, utilizing a thread pool for message digestion can improve performance and reduce latency. Frontend servers can also be used to decouple game logic from connections, allowing for scalability and efficient management of client connections. Efficient connection management and message digestion are crucial for a successful MMO experience.
