Mastering Latency Metrics: P90, P95, P99
Latency metrics play a critical role in evaluating the performance of a service or application, by observing P90, P95 and P99 latencies we can identify potential bottlenecks to optimize the user experience.
We should know how important it is to get our services and applications under a particular latency period and also have an SLA ( Service Level Agreement ).
Imagine you’ve built a robust backend system that’s been thoroughly tested, meeting all functional requirements.
You’re excited to roll it out to production. However, just before deployment, you are requested for details on the system’s performance metrics:
What’s the average (Mean), middle (Median), and maximum latency?
Additionally, you want to know at what level of load the system was tested
