How to measure Latency?

Heinrich Hartmann - P99 CONF - 2021-10-06

Introduction

• Inspiration for this talk comes from Gil Tene - How (NOT) to Measure Latency?
  Slides (London 2013) / Video (StrangeLoop 2015) / Blog - HighScalability 2015

• I have been talking about Statistics and Lantency for the last years:
  • Statistics for Enginees (2014..2019)
  • Latency SLOs Done Right (FOSDEM 2019)
  • State of the Histogram (SLOConf 2021) / Circllhist (paper)

In this talk/blog I am collecting my learnings, and bring them into a fresh form.
