The perfect Varnish configuration for WordPress, Joomla, Drupal & other (common) CMS based websites

Updated on December 15th, 2021

IMPORTANT: Read this before implementing one of the configuration files below (for either Varnish 3.x or 4.x+).

USE: Replace the contents of the main Varnish configuration file located in /etc/varnish/default.vcl (root server access required - obviously) with the contents of the configuration you'll use (depending on your Varnish version) from the 2 examples provided below.

IMPORTANT: The following setup assumes a 180 sec (3 minute) cache time for cacheable content that does not have the correct cache-control HTTP headers. You can safely increase this to 300 sec (or more) for less busier sites or drop it to 60 sec or even 30 sec for high traffic sites. It obviously depends on your use case.

My issues with Modules

In researching topics for RailsCasts I often read code in Rails and other gems. This is a great exercise to do. Not only will you pick up some coding tips, but it can help you better understand what makes code readable.

A common practice to organize code in gems is to divide it into modules. When this is done extensively I find it becomes very difficult to read. Before I explain further, a quick detour on instance_eval.

You can find instance_eval used in many DSLs: from routes to state machines. Here's an example from Thinking Sphinx.

Redis 4.2 roadmap

1. Redis Cluster

• Speed up key -> hashslot association. Now makes RBB loading 4x slower when there are many small keys.
• Better multi data center story
• redis-trib C coded and moved into redis-cli
• Backup / Restore of Cluster
• Non blocking MIGRATE (also consider not using 2X memory)
• Faster resharding
• Bug fixing and stress testing to bring it to next level of maturity
