The three distinguishing characteristics of httperf are its robustness, which includes the ability to generate and sustain server overload, support for the HTTP/1.1 and SSL protocols, and its extensibility to new workload generators and performance measurements.". has led to variations in response times with increasing load on the server. A sample invocation for a total of 5,000 connections, each one of which should try to issue 50 requests, looks like this: The first line of output will show arguments that have been assigned their defaults because you haven’t specified them: Unlike curl-loader, httperf doesn’… Performance Testing with Httperf, Here I'm going to cover basic usage for httperfrb, which I wrote to assist in automating performance testing with httperf.
