Thousands of autoloading transients

  • We have a new client who must have used this plugin in the past. Their site was extremely slow on a page load and we found 2,411 entries in the wp_options table consisting of autoloading transients such as …

    _site_transient_brute_loginable_bacc42e348edb9f61cff8a1180d6c5ca (0.39Kb) Autoloaded   
_site_transient_brute_loginable_fa385c494d7499dc92db2838dc75f760 (0.39Kb) Autoloaded

_site_transient_brute_loginable_23c6ba2f32376f45db75eda8f20c1125 (0.39Kb) Autoloaded

    This data is using 0.5Mb and because the transients were not set to expire they are set to autoload which means that they are all loaded on every page load.

    Since WordPress v6.1 the “Dashboard – Tools – Site Health” check has started recommending that your site should be using a “Persistent Object Cache”?if they are loading more than 100Kb of autoloaded options / transients.

    If you’ve ever used this plugin you might want to check your wp_options table in your database to see if you have a plethora of transients like this that need to be removed.

    The all start with _site_transient_brute_loginable_ so are easy to find.
