Although you may be running a single-threaded test intentionally, I generally recommend using a multi-threaded load simulation tool versus Apache's ab tool [1].

Although you may be running a single-threaded test intentionally, I generally recommend using a multi-threaded load simulation tool versus Apache's ab tool [1]. My preference is wrk [2], especially since it provides for time-limited tests rather than request-limited. Another alternative is WeigHTTP [3], which is basically a multi-threaded replacement for ab.
