With the rapid growth of the Internet, network servers, especially Web servers, need to provide a large number of concurrent access services as the number of visitors increases rapidly. For example, Sohu receives millions of access requests every day. Therefore, CPU and I/O processing capabilities will soon become a bottleneck for servers that provide large-load Web Services.Under the idea of Server
