Comment (by cohosh):

 I made some alterations to the bridgetest:
 https://github.com/cohosh/bridgetest/tree/snowflake_health

 This makes a connection through 100 snowflakes and attempts to download a
 1MB file. The script `infer-throughput.py` has been modified to process
 the 100 pcap files associated with these connections and output a CSV file
 that contains the bytes downloaded over time. The script `throughput.R`
 turns this CSV into a CDF plot and some stats and outputs the number of
 snowflakes that failed (we were unable to build a Tor circuit through
 them).
