netpoll

Specifically designed for RPC scenarios, it reduces goroutine overhead and context-switching costs under high concurrency, as evidenced by its integration in production frameworks like Kitex and Hertz.

The IsActive API allows for precise connection liveness checking, enabling more effective pool management than standard net.Conn, which lacks this feature.

LinkBuffer provides nocopy APIs for streaming reads and writes, minimizing memory allocations and improving throughput in data-intensive RPC operations.

Includes gopool for goroutine management and mcache for memory reuse, reducing overhead and improving performance in high-load microservice environments.
