4x High Performance for Drupal - Step by Step - The ultimate beginner's guide


This is the ultimate beginners guide to High Performance for Drupal.


Your newly launched Drupal site is slow, what can you do?

This you'll learn here in a practical, easy to understand and useful way for both Drupal 7 and 8.

Drupal Performance can be divided broadly into 4 Categories:

  • Server
  • Client
  • Modules
  • Database

This session will show how to setup technologies for getting the expected base line performance for each of those and giving a good overview of what can be tweaked.

  • Server: OpCache / APC, APCu, Memcache / Redis, Varnish
  • Client: GZIP, Fast JS, Minimal CSS, Caching Headers, AJAX/PJAX, BigPipe
  • Modules / PHP / Drupal Code: Common problems, XHProf (fast installation), Custom Caching, Block Cache Alter, Render Cache, Performance Core Patches, SuperCache, Chained Fast
  • Database: Common Tweaks, InnoDB, Slow Query Detection, Slow Query Fixing

The session will show step-by-step approaches how to gradually make the site faster.

It is aimed at beginners and will give a broad overview to know where to look for performance problems and what to do.

This is targeted as a Drupal 7 and Drupal 8 session at the same time. Both audiences will get plenty of alternatives for things.

I am happy to share this session with a co-presenter if someone wants to target beginners, I felt a beginner session was still missing for this year.

It will be great fun!
