 Hi!

 Tor 0.3.4.9, on Debian stretch (Thus linked against libssl
 1.1.0f-3+deb9u2), sometimes bootstraps slowly.

 The times in the following samples are times (in seconds) from process
 launch (with a non-existing data directory) until PROGRESS=100 is reported
 in a getinfo status/bootstrap-phase:

 9, 9, 7, 45, 11, 16, 17, 9, 21, 6, 10, 15, 44, 15, 15, 15, 7, 14, 7, 8,
 12, 8, 14, 13, 8, 8, 11, 6, 8, 8, 35, 16, 11, 7, 7, 9, 7, 8, 13, 10, 8,
 10, 14, 12, 15, 6, 7, 8, 91, 24, 13, 10, 10, 10

 Most of the bootstraps are quite comfortable in the sub 20s, but there are
 a few outliers well above 30 seconds.

 This is on an unfiltered network, with low latency and plenty of
 bandwidth.
