Dragon Speed Doctor

Find out which plugins are slowing your WordPress site — measured, not guessed.

Dragon Speed Doctor is the modern successor to the long-gone P3 Plugin Performance Profiler. Press one button and it times your site with each plugin briefly held out of internal test requests, then tells you in plain English what each one costs — on the front end and in wp-admin — alongside a per-plugin script and stylesheet weight audit and database-bloat signals. Visitors are never affected; only the doctor's own signed internal requests are measured.

• Per-plugin timing attribution with honest confidence ranges (and an honest "inconclusive" when the server is too noisy).
• Asset audit: what every plugin ships to your pages, with render-blocking flags.
• Database signals: autoloaded-option weight and probable owners.
• Plain-English verdicts with Low / Medium / High badges, plus before/after comparison across scans.
• WP-CLI: wp speed-doctor scan. No external services — everything runs on your own server.
