基于完成端口模型的网络服务器性能优化研究

Research on Performance Optimization of Network Server Based on the Completion Port Model

完成端口模型(IOCP)在各种网络并发I/O处理的模型中,是效率最高的。为进一步提高完成端口的执行性能,可以对模型处理流程中的各步骤作进一步优化。连接池技术可以实现SOCKET的重复利用。对象池技术改善完成端口模型对内存资源的利用效率,WSARecv函数采用零字节投递处理重叠I/O,可降低操作系统资源开销。

The completion port model(IOCP) is the most efficient model for concurrent I/O processing in a variety of network.In order to further improve the performance of the completion port, we can further optimize the steps in the process of model processing. Connection pool technology can be used to achieve the reuse of SOCKET. Object pool technology to improve the completion port model of memory resource utilization efficiency, WSARecv function using zero byte delivery processing overlap I/O, can reduce the operating system resource overhead.
