How to Measure Latency

Measuring Latency for Monitoring and Benchmarking purposes is notoriously difficult. There are a lot of pitfalls with collecting, aggregating and analyzing latency data.

In the talk, we will make an effort to visit this topic from a top-down perspective and compile known complications and best-practice approaches on how to avoid them. This will include:

  • Measurement Overhead
  • Queuing effects – Coordinated omission
  • Histograms for Aggregation and Visualization
  • Percentile aggregation
  • Latency bands and burn-down charts
  • Latency comparison methods (QQ Plots, KS-Distance)
