QPS query per second)Queries per second QPS is a measure of the traffic processed by a specific query server within the specified time. On the internet, the performance of machines serving as Domain Name System servers is often measured by the query rate per second.

On the Web server side, the daily traffic is huge. In a non-production environment, stress testing of the server is required, typically using a background thread and sleep mode to simulate the stress on the line. Here a simple QPS test code is implemented using Scheduledexecutorservice.Qpsproxy:Import Com.google.common.base.preconditions;import Org.apache.commons.lang3.math.numberutils;import Org.slf4j.logger;import Org.slf4j.loggerfactory;import Java
Reveal the secrets of increasing QPSGuideIn actual development, many people fear that the QPS of the system increases, because they think that the system will be suspended if the QPS is too high. Based on this mentality, they will try to reduce the system's request volume as much as possible, some people may even place a lot of processing in the service for processing. In this way, when an external request
will be required to start 20 threads. That is, starting 2 threads per second.Number of cycles : The number of times each thread sends a request. If the number of threads is 20 and the number of cycles is 100, then each thread sends 100 requests. The total number of requests is 20*100=2000. If "Forever" is checked, then all threads will continue to send the request, one to choose to stop running the script.Setting a reasonable number of threads can have a decisive impact on meeting the test targ

The following two figures show the stress tests I conducted with AB. One is the 100 requests with the concurrency of 1, and the other is the 100 requests with the concurrency of 100.
