Dragon Speed Doctor
Find which plugins are slowing your WordPress site — measured on your own server, explained in plain English.
Features
What Dragon Speed Doctor does
Per-Plugin Timing
What each plugin costs on the front end and in wp-admin, as honest measured ranges
Asset Audit
Every script and stylesheet on your pages, attributed to the plugin that ships it, with render-blocking flags
Database Signals
Autoloaded-option weight and probable owners, a common hidden slowdown
Plain-English Verdicts
Low, Medium and High impact badges, sorted worst first, no jargon
Before & After
Scan before updating plugins and again after, and see exactly what changed
Dependency Awareness
Plugins that cannot be separated are measured together and labelled honestly
Honest Confidence
Says "inconclusive" when the server is too noisy, instead of inventing a number
WP-CLI
`wp speed-doctor scan` for scripted or scheduled diagnosis
No External Services
Everything runs on your own server; nothing is sent anywhere
Requirements
- · WordPress 6.2 or newer

Changelog
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.
