PHPDD23: Practical Debugging and Performance Profiling

PHPDD23: Practical Debugging and Performance Profiling

Finding and fixing bugs is part of the daily work in software development.
This talk is about a methodical approach to finding bugs.
In particular, we will focus on performance profiling, as there are particular challenges here, and some of the common debugging tools such as XDebug are of limited use.
We will discuss various tools as well as their use to efficiently track down performance issues.
We will look at the whole stack of the application, including IO and database.

    problem, without performance hit normal mounts not possible, !!! lots of workarounds for emulating mounting SLOW sshfs gRPC-fuse virtiofs reality
  5. Unstable Foundation Modify some things in the codebase "which might

    improve things" do roughly the same steps, but not exactly
  6. var_dump() die() am I in the right codebase? (die() in

 am I in the right fi le? 
 is the opcache caching too agressively? 
 how often is this method called?
  7. function B.2 throw new \RuntimeException("FOO"); read a stack trace function

    A function B.1 function C function main function main() { a() } function a() { b1(); b2(); } function b1() { c () } Stack
  8. Stable Foundation Hypothesis Design Experiment Execute Experiment Valid Knowledge write

    it down run an experiment to establish foundation must give 100% reliable results
