I've built an ISO from experimental (Tor 0.2.5.7-rc), booted it 10
times with a pretty fast and stable Internet connection, and:
* 9 times, Tor bootstrapped reasonably quickly
* 1 time, it took 5 minutes to go from 50% to 100%
This doesn't confirm the "half of the times" failure rate, but it's
indeed bad enough to be worrying. I'll try to find time to do the same
test tomorrow, on the same Internet connection, with Tails 1.1.2 and
in the automated test suite.
It seems that everytime there's a problem, connections to
[scrubbed]:443 are attempted during bootstrap. I'm assuming that these
are client connections. Might it be that 0.2.5.x is badly affected by
circuit requests while bootstrapping?
IMO, next step is to report a bug upstream, so that Nick, Andrea or
Roger can have a look at it.
