1 / 5
The p50 latency is also known as the ___.
-
-
-
-
p50 is the median: half of requests are faster and half slower, giving a typical-case view.
2 / 5
p99 latency means 99% of requests are faster than that value and 1% are ___.
-
-
-
-
p99 captures the slow tail: only 1% of requests exceed it, which still affects many users at scale.
3 / 5
The slow end of the distribution affecting a minority of requests is called ___ latency.
-
-
-
-
Tail latency (p95/p99/p99.9) describes the worst experiences; it often dominates user perception even when averages look fine.
4 / 5
Averages can mislead because a few huge outliers ___ the mean.
-
-
-
-
A handful of very slow requests pulls the average up (or hides a bad tail), so percentiles give a truer picture than the mean.
5 / 5
Tracking p99.9 instead of p99 surfaces even rarer ___.
-
-
-
-
Higher percentiles like p99.9 expose rare but severe slowdowns that p99 may smooth over, important for strict SLOs.
