> Currently, the only option in {{PerformanceEvaluation}} is to print latency percentile summary at the end, and it is also not suitable if we are testing for a long duration (as all the timings are collected in memory). There should be an option to dump the latencies with a timestamp as CSV to a file so that this allows a detailed analysis on the generated data, such as:
> - Percentile calculation at the desired precision on the latencies 
> - Latencies over time
> - Histograms
