Local is painfully slow

What issue or error are you experiencing?

Local is painfully slow on my Windows 10 installation, and it never used to be this bad. It’s so slow within the Wordpress admin that it’s completely unusable with it taking minutes to load an admin page or perform an action. It’s only the Wordpress site running via Local that is slow and nothing else.

I have tried everything on the following page: Troubleshoot: Performance Issues - Local

What steps can be taken to replicate the issue? Feel free to include screenshots, videos, etc

I’ve noticed that the issue seems to be centred around the “load-styles.php” file when checking Chromes network log - you can see on this instance that takes over a minute to load a simple wordpress post in the admin:

Does anyone have any suggestions as to what might be causing this?

Hi @mattrosebcc

If the issue is with this specific site and that load-styles.php file, then there are a handful of common culprits you could check:

  • You could try boosting memory. We have steps for that at the bottom of the performance help doc above.

  • Try disabling all plugins and see if it speeds back up. Then you know it’s a plugin issue and you could try turning them on one at a time to see what happens. Or you could try using something like Query Monitor or this plugin to see if that helps narrow things down.

  • If you swap the theme to a default theme does the site speed back up? That could show a theme conflict at play.

  • Are there any overly large tables or bloat in the database that could be optimized?
