Because of that, when wp_options gets bloated, especially with values that have autoload=yes, and every thread ends up transferring that much more data, overall performance decreases, and db traffic goes up. Transients are typically (with few exceptions) added as autoload=no. This keeps performance in check. However, there's one notable exception, and on our server, it's 120 rows all dedicated to a single transient, with over 30KB of data in total that gets transferred for no reason. That transient is `""browser_"" . $key`, and it's only used by `wp_check_browser_version()` in `wp-admin/includes/dashboard.php`. There's no reason at all for it to use autoload=yes." defect (bug) new normal Options, Meta APIs 4.1 normal performance
