Site health
How to tell server time from front-end weight, measure what each plugin actually costs with leave-one-out profiling, read the results honestly, and prove the fix with a before-and-after scan.
Site health
Why sites get slower one update at a time, how to keep a measured baseline, scan after every update, and get an alert that names the change responsible, only once a second scan confirms it.
Every Speed Doctor action now checks its own security token and your permission. Scans measure exactly as before. • Request values are read through WordPress's own sanitizers. • The measurement loader accepts a scan token only for the exact page it was issued for, and refuses any request whose address it cannot read whole. • Uninstalling one copy of the plugin while another copy is active no longer stops with an error.
