What we found

critical

Requests are failing

1095 requests returned a 5xx status and 0 requests raised a PHP error in this window.

Every one of these is a visitor who saw an error page or a broken checkout. They are the first thing to fix: they cost money directly, not just speed.

What to do: Open the failing requests in the console, take the newest one and follow its stack: the trace holds the query, the outbound call and the error that ended it.

Database queries that cost the most

These 98 fingerprints account for 10.9 s of database time in the window. Literal values are stripped, so no customer data is stored or shown here.

A single missing index is the most common cause, and the cheapest to fix.

What to do: Run EXPLAIN on the first fingerprint. If it scans the table, add the index it asks for.

info

Where the time goes, by plugin and theme

Measured on 39 995 profiled requests.

This is the answer to "which plugin is slowing the site down" — measured on real traffic, not on a synthetic page load.

What to do: Take the top entry and ask what it does on every request. Plugins that only matter in the admin should not be loading on the shop.
