Server Response Time at Percentile Calculator

Calculate P50, P95, and P99 server response times from latency distributions. P99 = slowest 1% of requests. For SLA purposes, P99 < 500ms is a common target for web APIs.

How It Works

Calculate P50, P95, and P99 server response times from latency distributions. P99 = slowest 1% of requests. For SLA purposes, P99 < 500ms is a common target for web APIs

Each component has a specific meaning:

  • Latency distributions — The latency distributions recorded for the scenario being assessed.

Note: Interpret the server response percentile result against the thresholds and context described above.

How to Use

Enter the latency distributions for the scenario you are assessing. Calculate P50, P95, and P99 server response times from latency distributions. P99 = slowest 1% of requests. For SLA purposes, P99 < 500ms is a common target for web APIs. Use the server response percentile result to inform your calculation.
