Be careful when using Arc Lamp profiles from the last few weeks in side-by-side comparisons, because of T389243. \cc @ori

In T389243#10648713, @Krinkle wrote:

This is causing performance.wikimedia.org flamegraphs to show bogus data [on PHP 8.1].

Specifically, it means we have no telemetry [in PHP 8.1] on the first few whole seconds of a response — which for the majority of requests, is the entire duration of the response.

Ack, thanks for the heads up.
