Support » Everything else WordPress » The Limitations of WordPress

  • I was wondering if there’s a stat sheet hiding on this site somewhere that lists what the limitations of WordPress are – what sort of usage it can cope with before it can’t cope any more or starts to suffer?

    For example, if someone was using a single WP installation and had 10,000 users you would expect the post editor page to struggle at least a bit as it would need to load 10,000 names in the author drop down box every time the page loads. Which would also put a lot of stress on the database as it scans it.

    Is there a spec sheet that states information such as how many users or posts is the limit before a strain is put on WP? Obviously, the server will have a large bearing on any thing like this, but it would be really helpful to get some sort of idea or benchmark 🙂

    You’re really only limited by the resources of your server. Obviously, you’ll reach a point when you’ll need more space, bandwidth, RAM, or CPU. If you continue to grow, you’ll eventually have to graduate from shared hosting to VPS and dedicated, which is true of any site built around a database.

    The only known technical limitation at this point is that performance may begin to noticeably decrease if you have tens of thousands of pages and employ either the /%category%/%postname%/ or /%postname%/ custom permalink structure. More info:

    This will be corrected in a future version of WordPress, though it’s not a high priority as it will require a rewrite of the entire permalink system and you’ll need tens of thousands of pages to notice any impact.

    Thank you! That link was very helpful! I did not know that.
