Comment (by karsten): Dennis brought up the questions whether failed measurements are included in the CDF-TTFB graph or not. They are not right now, but we might consider including them with `TTFB=Inf`. The result would be that the curve doesn't go to 100% when there are failed attempts. That would give us an idea of when to expect the first byte in x% of measurement ''attempts''. However, a possible downside might be that different time periods are harder to compare when there was a higher rate of failures in one period. On the other side, maybe that's useful information. I [https://trac.torproject.org/projects/tor/attachment/ticket/33076 /onionperf-cdf-ttfb-2020-02-11.pdf attached] two variants of CDF-TTFB, one containing ''all successful'' measurements as before and one containing ''all'' measurements including the failed ones. The difference is really small in this case, visible for example in the op-us onion graph. It might be more visible in other cases. Leaving this here for discussion. This might be a non-standard way of using ECDFs and therefore harder to understand and possibly harder to make with matplotlib. But if there's agreement that it would be good to have, we should try to make these graphs. -- Ticket URL: <https://trac.torproject.org/projects/tor/ticket/33076#comment:21> Tor Bug Tracker & Wiki <https://trac.torproject.org/> The Tor Project: anonymity online
