Function: percentile()
percentile(
sorted,fraction):number
Defined in: backend/src/loadtest/metrics.ts:36
Nearest-rank percentile on a sorted copy.
Nearest-rank rather than interpolated, because an interpolated p99 reports a latency nobody experienced. For a capacity envelope the honest question is "what did the slowest one percent actually see", and that has to be a real observation.
Parameters
sorted
readonly number[]
fraction
number
Returns
number
