A simple HTTP performance test toolWrk.gitA simple HTTP benchmark tool that can do a lot of basic HTTP performance testing.A good feature of wrk is that it can use a very small number of threads to press out a lot of concurrency.The reason is that it uses some operating system-specific high-performance IO mechanisms, such as SELECT, Epoll, Kqueue, and so on.
In fact, it is a reusable Redis AE async
