Benchmarking PHP modules

This paper presents how C programming language could be used for this type of tasks, created as PHP module and then get imported in the PHP language. The purpose of this paper is to show how and when is better to build PHP modules in C, instead of normal PHP functions, and to show negative sides of this type of programming. Profiling, as an important aspect of finding application bottlenecks, is also discussed. Profiling systems like Xdebug, Qcachegrind and Webgrind are also elucidated.
