Together with its predecessor, Torperf, OnionPerf has been used to measure long-term performance trends in the Tor network since 2009. It is also being used to perform short-term performance experiments to compare different Tor configurations or implementations. OnionPerf uses multiple processes and threads to download random data through Tor while tracking the performance of those downloads. The data is served and fetched on localhost using two TGen (traffic generator) processes, and is transferred through Tor using Tor client processes and an ephemeral Tor onion service. Tor control information and TGen performance statistics are logged to disk and analyzed once per day to produce a JSON analysis file that can later be used to visualize changes in Tor client performance over time. @@ -180,7 +198,7 @@ For example, the hard-coded traffic model generated by OnionPerf and executed by ### Sharing measurement results -Measurement results can be further analyzed and visualized on the measuring host.
