Qaiyo Web Performance Surgeon

Most performance tools tell you that your site is slow. Qaiyo Web Performance Surgeon tells you what is slow, where it comes from, and how much you would save by fixing it — then fixes the safe ones in one click.

It measures a real, anonymous visitor render (not your logged-in admin view) by running a tokened loopback request, and attributes every cost back to the exact plugin, file and line responsible.

Features

• File- and function-level attribution — every slow query, hook and asset is traced to the exact plugin, file and line responsible, not just “the database is slow”.
• Measures the real visitor render — a tokened, anonymous loopback captures the logged-out front-end page, not your admin-skewed view.
• Estimated time saving per finding — every issue is ranked with an honest millisecond estimate, so you fix the biggest wins first.
• Database profiling — per-query timing, duplicate-query detection and bloated autoloaded-option detection.
• Hook and callback timing — per-callback cost with plugin attribution, captured with low overhead (no per-call backtraces).
• Blocking HTTP detection — flags slow external requests made while the page renders.
• Asset inventory — enqueued scripts and styles listed with their owning plugin.
• Real browser metrics — Largest Contentful Paint, Cumulative Layout Shift, long tasks and navigation timing from an actual browser render.
• Image checks — finds images served far larger than they are displayed (with the wasted kilobytes) and images that render without width/height, which makes the page jump.
• Duplicate asset detection — spots the same library shipped twice by different plugins, or the same file registered under two handles.
• Server & environment tab — the performance checks WordPress itself runs (object cache, page cache, PHP and database versions, cron, debug mode), collected in one place.
• Compared with your last scan — every scan shows whether server time, query count and findings went up or down since the previous scan of the same URL.
• Performance score on your dashboard — your latest scan is condensed into a single 0–100 score on a speedometer gauge, shown in the shared Qaiyo ecosystem dashboard widget (provided by Qaiyo Admin Booster) so you see how the site is doing without opening the plugin.
• Safe one-click fixes — reversible toggles for common wins; no source files are ever modified.
• Zero overhead on live traffic — measurement only switches on after a scan token has been validated against the record that issued it; normal visits pay nothing.
• Available in 11 languages.

What it measures

• Database — every query with its execution time, paired to the calling plugin/file/line (via SAVEQUERIES), plus duplicate-query and autoloaded-option detection.
• Hooks — per-callback timing with plugin attribution, captured without per-call backtraces (low overhead).
• HTTP — outbound requests made during render, flagging blocking external calls.
• Assets — enqueued scripts and styles with their owners.
• Browser — real LCP, CLS, long tasks and navigation timing, captured from an actual browser render.

Diagnosis and one-click fixes

The rule engine turns raw measurements into ranked findings with an estimated time saving for each, and offers safe, reversible one-click fixes for common wins:

• Disable the emoji detection script
• Disable wp-embed.js
• Remove jQuery Migrate
• Dequeue front-end Dashicons
• Stop autoloading a bloated option
• Remove the legacy RSD / Windows Live Writer links from the page head
• Turn off XML-RPC (only offered when nothing on the site appears to need it)
• Stop self-pingbacks when you link between your own posts
• Remove the “?ver=” query string from static assets, for caching layers that skip versioned URLs

Every fix is a toggle you can undo — no source files are ever rewritten.
