The server (192.168.1.215) and client are in the same LAN. This is very good for 100 mbps networks.

tested 691180 data records reserve sufficient memory space for each insert of a large amount of data. For the deque storage allocation assumption, observe the memory allocation graph and the previous graph in this test. We need to further quantify this test. How can we improve the performance of memory allocation? The following figure shows that the capacity increases as data increases: When adding data, the efficiency of adding the capacity is basically the same in the execution of ve
