When we run a performance test for an operation, the results are displayed in the form of percentile in Performance Report. The percentiles are 50th, 70th, 80th, 90th and 95th. Which percentile should be used for calculating the time taken by the action?
Thanx in advance.
A highly advanced bug is indistinguishable from a feature.
1) find some who is good with statistics to help you understand.
2) read the first several "User Experience, not Metrics" articles on my site (www.perftestplus.com), there is a pretty good description of percentiles in there.
3) use the highest one that is statistically reasonable (i.e. if you have 10 measurements, the 95th percentile is a fabricated number).
