Clean your site's database Your WordPress database grows with time and often contains a lot of unnecessary data. Clean your database with Templ Optimizer and see the effect on your database size and experience the difference in performance. Add high-performance database indexes As your site grows, WordPress's default database keys can leave MySQL scanning large tables to find data. Templ Optimizer can add high-performance keys to the core WordPress tables (posts, postmeta, comments, commentmeta, termmeta, users, usermeta and options) so WordPress finds what it needs faster. The change is safe and fully reversible: revert to WordPress's standard keys at any time. On large tables, use the WP-CLI command to avoid browser timeouts. This capability is inspired by the excellent Index WP MySQL For Speed plugin. Diagnose slow outbound HTTP requests Sometimes a site is slow even though CPU load and database queries look fine. A common cause is PHP waiting on slow third-party HTTP calls (wp_remote_get() and similar): these run synchronously, so a slow remote server can hold up a whole page. Enable HTTP request diagnostics to capture completed WordPress HTTP API calls into a dedicated, bounded log (7 days / 100,000 records per site), then find the slowest calls, the destinations with the highest cumulative blocking wait, and the plugin or theme responsible. Only the destination host and a redacted path are stored — never query values, headers, cookies or response bodies. Manage it from the admin app or with WP-CLI (wp templ-optimizer http enable|status|list|summary|show|clear|disable). Tweak WordPress & plugin settings Contains many smart tweaks and settings for WordPress as well as some of the most popular plugins. Free up more resources for your site to handle visitors and speed up your website. Got a feature request? Are you missing a feature? Do you have ideas on how Templ Optimizer can be improved?
