P95 Latency
The value at the 95th percentile when all request latencies are sorted from lowest to highest, used to measure tail latency and an important design constraint metric for real-time control systems.
Core Facts
Timeline (last 90 days)
Setting a P95 latency baseline for object storage and triggering an alert when the P95 value deviates significantly from the historical baseline can help teams spot problems in the early stage of degradation (for example, latency doubling without a full outage).
On the AKV engine, output throughput improves by up to 1.2x and P95 request latency speeds up by 1.5x.
For technology selection in production environments, it is recommended to use P50/P95 latency rather than average values to evaluate real-time user experience, and to measure throughput under load testing.
It is recommended to measure both P50 and P95 latency during evaluation, as P95 reflects the real-world experience under high load or long-context scenarios.
