PHP performance has improved dramatically from PHP 5 to PHP 7. Gone are the days where PHP applications are slow because of PHP itself. So where does one look when a PHP application starts to slow down?
We need to have the ability to quantify and measure performance before we can make meaningful optimizations. Otherwise, we are simply guessing and may be focusing on something that doesn’t need to be optimized.
In this session, we’ll walk through concepts like profiling and instrumentation. We’ll learn about the performance impact profiling has on the code being profiled. We’ll also discuss resources and tools developers have at their disposal to help measure the performance of their PHP applications.
