Chapter 6. Stress/Load Testing PHP Applications

After an application is developed, tested, debugged and then profiled, it is time to bring it to production. However, before going to production, it is best practice to stress/load test the application.

Using these results, we can optimize the application, web server, database, and our caching tools to get a better result and process more requests.

In this chapter, we will load test different open source tools on both PHP 5.6 and PHP 7 and compare these applications' performance for both versions of PHP.
