Uses epoll on Linux and kqueue on BSD for efficient I/O multiplexing, handling massive concurrent connections with minimal resource overhead as demonstrated in performance benchmarks.

Configurable worker goroutines leverage all CPU cores effectively, with default settings matching the host's core count for optimal throughput in multi-threaded scenarios.

Plug-in architecture allows easy integration of custom data framing, evidenced by included WebSocket and Protobuf plugins and the ability to implement the Protocol interface for tailored protocols.

Implements dynamic ring buffers that expand as needed, reducing memory fragmentation and improving performance for variable payloads, as highlighted in the network model.
