How to Build a High-Performance TCP Server from Scratch | HackerNoon
Briefly

Building a high-performance TCP server using the .NET Socket class requires a keen insight into socket mechanics and connection management to enhance throughput and minimize latency.
The implemented TCP server effectively handles heartbeat messages from numerous IoT devices, demonstrating capability in maintaining a responsive, efficient system while processing thousands of requests.
Through this exploration, we compare our bespoke .NET socket server's performance against Kestrel, illustrating that optimizing socket usage can yield high throughput and low latency communication.
Latency and throughput serve as the primary performance metrics for our TCP server, emphasizing the importance of efficiently handling heartbeat messages to ensure timely responses.
