W3 Total Cache (W3TC)

W3 Total Cache supports APCu and Memcached for multiple servers.

I really like the way it integrates with Nginx - simple and non-intrusive. It creates a file in nginx.conf www root that I must include in my custom nginx configuration.

W3TC Plugin Config

include /path/to/wproot/nginx.conf;

# W3TC Plugin Config
include /var/www/vhosts/hostingtipp.ch/httpdocs/nginx.conf;

Setup W3TC on NGINX

Plugin has great and advanced features as New Relic integration for monitoring, cache purging for Varnish - insignificant to us, has great CDN support both for CloudFlare with extension and with MaxCDN, extension to play nice with WordPress SEO by Yoast plugin that we use extensively.

In the future, I can easily switch storage backends, if needed.

All of this functionality is possible to be achieved with separate plugins.

WP Super Cache

WP Super Cache caches to disk and has no way of controlling user-land object or db cache - it is way inferior to W3TC.

Alternative, more focused solutions

APCu Object Cache Backend is clean and small Drop-in plugin, with really only one file object-cache.php.

Install and then we must type:

cd /var/www/vhosts/hostingtipp.ch/httpdocs
mv wp-content/plugins/apcu/object-cache.php wp-content/object-cache.php

WP-FFPC supports both PHP Memcache and Memcached extensions.

1. Moram W3TC zbog CDN i New Relic-a (ne koristi mi ništa jer je to Javascript verzija), npr Ugasi full-page cache, ostalo ostavi

2. Moram APCu jer je to najbrži object cache (i nije najbrži) Takođe ga mogu koristiti za full-page cache (umesto nginx recimo)

3. Ostaje tema - full page cache-a

Cachify

Cachify is indirectly recommended by KeyCDN authors, but to me it is too much of a “black box”. Can work with nginx and it’s memcached module, as explained in this gist by plugin author.

It doesn’t work with APCu nor memcached with PHP. So, avoid it. Ali u 2023 izgleda da sad radi sa APCu

Browser caching of static assets

# Cache static content

location ~* \.(?:css|js|jpg|jpeg|gif|png|ico|cur|gz|svg|svgz|mp4|ogg|ogv|webm|htc)$ {

  access_log off;
  add_header Cache-Control "public";
}

Very simple explanation of browser caching headers.

Ultimativno browser caching je da cache nikada ne expire, a da nako modifikacije menjamo ime asset-a odnsono radimo cache-busting (aka fingerprinting) dodavanjem nekog query stringa. Ovakav proces je objašnjen u članku Your Cache Headers Could Probably be More Aggressive

Object Cache SLOWED down the site

One last thing to add regarding W3 Total Cache, do not enable Object Cache. That bypasses the WordPress Transients API which the Datafeedr plugins rely on for storing data to reduce the number of API requests required to build and update your products.

? Thanks for that Eric. I’ve found problems in the past when using W3 Total Cache object cache or database cache.
