95th Percentile in Performance Testing
Can anyone tell me why percentiles are used in Performance testing report?
what is the use of 85th, 90th, and 95th percentile?
Re: 95th Percentile in Performance Testing
Because they're good indicators of performance?
Think of a bell curve representing all of your users' response times during a test. Do you want to represent half of your users? Likely not...
85% of your users? Maybe that's sufficient but it's ultimately up to your clients.
We test against 95th percentiles because we want response times to be equal or better than requirements for almost all of our users.
