How Much Content Can a Craft Site Have?

People often ask how much content Craft CMS or Craft Commerce can handle with specific numbers in mind for entries, users, orders, assets, and other element types.

Craft’s license doesn’t put any limitations on your content, but the number of elements it can support depends on how your site is built, optimized, and hosted.

Craft CMS and Craft Commerce sites are in the wild, running smoothly with tens of millions of elements, and we’ve seen smaller sites struggle to keep up with modest amounts of traffic. The answer is usually “Yes, Craft can handle that,” but you should take care with a few things that maximize your site’s ability to handle a growing body of content:

Mind your site count #

Every site you add to an installation is generally a multiplier for the number of queries that need to be executed. A site with complex information architecture may trigger 200 queries for a single site but could generate 800 queries for a four-site installation. Consider your content modeling and propagation along with however many sites you plan to use.

Craft’s multi-site implementation is meant for a single Craft installation where each site shares some common content (entries, users, templates, etc.) with each other. It is not designed to manage completely independent sites with no relationship to each other under a single Craft installation.

Craft’s multi-site implementation is not meant to be infinitely scalable. Craft 5 has a soft-limit of 100 sites in a multi-site installation. You probably shouldn’t get anywhere close to that, much less go over it.

If you want to use Craft’s multi-site capabilities to sell “sites” to multiple clients, you’re probably using the wrong tool for the job.

Infrastructure and resources #

Make sure you’ve got adequate infrastructure with enough resources for PHP, the database, Redis, and your traffic patterns.

Utilize smart caching strategies #

The fastest requests are the ones where PHP and a database never get involved. If you can return cached content to a user, you should. Your caching strategies should balance how the site is built and deployed with how it needs to be used by each visitor.

Tune database indexes #

Tune them specifically for your site’s needs and queries. Craft provides a reasonable set of indexes for the most common types of queries a site might use. On modestly sized sites, any missed opportunities for index tailoring will probably go unnoticed. Those same issues, however, will gradually be amplified as the size of the database grows.

Be cautious with information architecture #

Content modeling complexity comes with more database queries. These queries may need more time to execute and closer attention to measure and optimize. A Plain Text field, for example, will be vastly more efficient than a Neo field inside a Super Table field in a Matrix field. Your site’s intended scale and resources should factor into content modeling design decisions.

Eager load your data #

Eager load your data wherever possible to maximize database query efficiency.
