My anecdotal experience is that it's about ~1 sec. for a "cold" request, and on the order of 10s of ms for repeated requests thereafter.

p99.9 was 100ms for me. p50 was 10ms.

Did 100k requests. Did these tests back in November during the preview. I imagine it has different latency now so those numbers are probably close to useless.

the first time i found it to be about 1-2 seconds, afterwards it's more 0-1s
