Note: for this discussion, we'll define very large sites as those with over 1,000 authors or 100,000 posts.

We are always cautious when people ask us, “Can PublishPress plugins run on very large websites.”

The quick answer is “Yes, we carefully optimize our plugins.”

However, answers are rarely that simple when discussing very large sites. Many factors need to be considered, including these:

  • The servers and databases running your site.
  • Other plugins and themes you have installed.
  • Issues with our plugins that may appear very rarely, and only on the biggest sites.

It is never easy for any website software to support large numbers of users and content. Optimizing software so that it works at scale is always a challenge. And WordPress does have some specific issues that can cause problems with very large sites.

Our advice is to test PublishPress plugins on a development site before going live. This is always good advice for all websites and all plugins, but we strongly recommend it in this scenario. If you find any issues, our support team will be happy to help.
