Using Blackfire.io to Profile Your Loading Time
Core Drupal developers already use performance analysis tools like XHProf and Blackfire.io to keep the code efficient, but generally a combination of too many contrib modules, inefficient database queries, or poorly written custom code can easily bloat the page's loading time by a factor of 3 or more. This session will provide you the understanding you need to use these tools, and provide a number of real-world case studies in how to use them to identify common performance bottlenecks, and potential remedies.
We will also discuss ongoing performance monitoring with tools like Blackfire and New Relic.
The examples will be presented from Drupal sites, but the tools are PHP specific, while the lessons apply to most web application programmers. The target audience is PHP developers with experience writing and debugging custom code.
