Load / Performance Testing Web Application - Httperf. Ruby. Send one request and check the response: use a dedicated physical machine separate from your subject under test to reduce intrusive latencies, and tail the server logs in separate terminal windows. When the Reply Rate is nearly equal to Request Rate then we can tell that the server is doing well. Autobench runs httperf a specified number of times against a URI, increasing the number of requests per second (which I equate to -c in ab) so that the response rate or the response time can be graphed vs. requests per second. As expected – this is the bread and butter of every load tester, where you test how a system behaves with a large number of users and what is the response time received for pages under different scenarios. Use "--hog" any time you're generating load from a separate host and your request rate is high.
