In the Winsock i/o model CPIO is undoubtedly the best performance, of course, is the cost high-performance system, the cost of considerable resources, in many aspects of connectivity and high data throughput applications that require high will use this model, so I Do not blindly believe that using this model. In specific applications such as long as the inheritance and then override a few virtual functions which can be, points to note are: 1, CPIO use multi-line said, so some resources must be synchronized 2, which would be unusual in the data transceiver allocate and free memory resources, this extraordinary resource allocation and released back consume some resources, so you can minimize this with a ways of minimizing the operation of this class are depleted, " Neicun pool"
