 > That looks fine to me Karsten (assuming you are using the LLVM hoist
 globals version of Shadow; prior ones probably won't work due to the issue
 described at https://github.com/bittorrent/libutp/issues/51).

 I'm using Shadow master (91fc269).  How do I know it worked correctly?
 Are there log messages indicating UDP vs. TCP traffic?

 without libutp? If so it would be worth investigating this as it probably
 would indicate a deeper problem.

 2.5 hours is normal.  I ran another simulation using vanilla, and that took as long as the other two simulations.  See
 -utp-combined.2.pdf attached].

 So, I wonder, shouldn't the black and blue line overlap more?  Is there
 anything else I should change in your branch to turn off uTP?
