This talk will begin with an outline of the differences between “profiling” code blocks and “benchmarking” a system or subsystem. After a short discussion on the purpose and intent of running benchmarks, we will see how to set up a benchmarking system, including the various tools and the experimental controls needed when doing comparative benchmarks. Finally, there will be real-life examples of comparative benchmarks between some major PHP frameworks, along with a description what the results indicate, and just as importantly what they do not indicate. (Although the example subjects are PHP-based, the principles apply to Ruby, Python, and Perl as well.)
