PHP On Steroids

  1. 1. PHP On Steroids: High Performance PHP “It's code, Jim, but not as we know it” Jonathan Oxer August 5th, 2004 Open Source Developers Conference Melbourne, Australia
  2. 2. When To Optimise Jon's 3 Laws Of Robotics Optimisation 1. Don't pre-emptively optimise – only do it when you need to in order to reach defined performance goals. Optimised code is (often) obfuscated code. 2. Don't guess which sections of your code need to be optimised. Measure with profiling tools such as APD or Xdebug, and run server benchmark tools with real data to give you hard figures. 3. Optimisation is a game of diminishing returns: go for the low-hanging fruit and keep going until it's “fast enough”. PHP On Steroids Jonathan Oxer
