Maybe I'm just stupid, but what are these numbers?

"HTTP benchmarks measured in round trip time for a cold start"

Soo, I'm guessing it's round trip time in milliseconds?

What is p0 to p100? Are they putting 0 to a 100 items? Are they putting 1 item into a dataset of size p..?

Percentiles of the measured startup times.

p100: 100% of the startups were slower, this is the maximum time they measured.

p50: 50% were slower than this

And so on to p0, which is the smallest measured time.
