> All the Caddy tests had metrics enabled

One of the great mysteries in (my) life is why people think that measuring things is free. It always slows things down a bit and the more precisely you try to measure speed, the slower things go.

I just finished reducing the telemetry overhead for our app by a bit more than half, by cleaning up data handling. Now it's ~5% of response time instead of 10%. I could probably halve that again if I could sort out some stupidity in the configuration logic, but that still leaves around 2-3% for intrinsic complexity instead of accidental.
