Summary of performance Test of Wangwang IM Advertising

Project: Wangwang IM performance test found in the test process in the server load and CPU and other performance indicators are very low. Tps never went up, even though the number of concurrent users was adjusted to a large number. After the advice of the master, it must be that the actual pressure did not go up. Is that right? So we started to verify. 1. Use ifstat and ifconfig on the server side to view the actual Nic operation and the actual flow of messages received. two。 Looking at the performance test data with almost the same traffic on other performance test machines, it is found that there is a significant gap between the two. So proceed to step 3. Switch the agent to the server side (originally the client press uses PCServer) for stress testing. As a result, tps finally reached a reasonable value.
