Performance
Numbers next to the release that moved them.
Response time went from 215 ms to 299 ms after v2.4.1 shipped at 16:24. Tenvey draws the release on the curve instead of leaving you to correlate two tabs.

Four numbers, each with a verdict.
Core Web Vitals are measured per URL on a throttled 4G profile, because that is the connection your slowest visitors are on. A value on its own means nothing, so every one is shown against the threshold it has to clear.
On /checkout, LCP sits at 2.1 s against a 2.5 s target and TTFB has risen from 240 ms to 410 ms. Two of the four are fine — the page does not say so in green and leave you guessing which.
A finding names the file.
“Optimise your images” is not a finding. Tenvey lists the six assets that load at full resolution before anything can render, what each one weighs, and what they cost: 1.8 s on a 4G connection.
The homepage ships 3.4 MB of images. Four files account for almost all of it.

When it runs
Performance carries 30% of the health score, the heaviest of the five, and currently scores 87.
- On every deployment
- A full run starts within two minutes of a release and is diffed against the previous one, so a regression is attributed while you still remember what you changed.
- Every six hours
- Pages that did not change are re-measured anyway. Third-party scripts and image CDNs get slower without you shipping anything.
- Every 60 seconds
- Time to first byte rides along with the uptime check, which is why the curve above has a point for every hour and needs no agent on your server.
