Description

The results of the #1919 Torperfs so far don't indicate a big difference of Tor clients picking the slowest or fastest guards. We should verify that the entrycons.py script is working correctly. I uploaded the entrycons_logs files of all 12 Torperf runs here (47M) for further analysis.

We should also correlate the choices of entrycons.py with what actually happened according to the control port's circuit history in the path data at: https://metrics.torproject.org/data.html#performance

Turns out that there is a bug here. I've written the verification script and it showed us that guard nodes were not being selected properly. We tracked it down to the fact that the entrycons.py controlled torperfs were still setting UseEntryGuards 0. I will commit a fix to this in another bug.
