>my suggestion would be characterizing the latency by providing several percentiles. I'd suggest using 10, 20, ... 90, 99, (and maybe 99.9 if we define the required number of samples as large enough to capture long tails). This is still a small number of data points that can easily be included in a test report. But it is effectively a quantized CDF and therefore captures the whole distribution including its shape reasonably well. [MG] Thanks for sharing your paper. I am not sure if this solution would make a good comparison base. As I see it, the test report has to be synthetic enough to allow easy comparison. Reporting a single number might not be enough, but reporting 10 numbers is too much imo.
