load performance testing tools

21st century is the century of the cloud, large-scale cloud networks have emerged, and in the next few years will be high-speed development, so that cloud-based systems will be more and more. If you want to develop a high-performance cloud system, server performance testing is an essential link. Today, we will introduce a new generation of server

Situations of 500 concurrent users Requests per secondd: 180.99 [#/sec] (mean) Time per request: 2631.662 [MS] (mean) Time per request: 5.263 [MS] (mean, internal SS all concurrent requests) Let's analyze the test results. First, compare the throughput. When the number of concurrent users is 190 reqs/s, the maximum throughput is 200,500. When the number of concurrent users is, the throughput is reduced, a
