 Replying to [comment:20 robgjansen]:
 > It may make sense that the amount sent on the wire is slightly more than
 the bandwidth 99th percentile bandwidth sent in Tor ( b/c control packets,
 packet header overheads, etc, are included in the amount sent on the wire
 but not in Tor's limits).

 Makes sense.  I attached another
 [https://trac.torproject.org/projects/tor/attachment/ticket/5336/task5336
 -bwburst-abs-2012-10-05.png graph] that shows cumulative fractions of the
 differences between 99th percentile and bandwidth burst.  That graph shows
 that there's hardly any difference between the three branches.

 > I believe the first few lines contain header info that explains the
 format of the csv. One of the columns has a timestamp and another has the
 system memory usage. You should be able to draw a memory-over-time plots
 with those two columns, and compare each branch in the same graph. (note
 that this is total system memory usage, so this would only work if nothing
 else is consuming memory on these machines - which should be the case if
 you used EC2)

 Okay, I attached a
 [https://trac.torproject.org/projects/tor/attachment/ticket/5336/task5336-mem-2012-10-05.png
 graph] for system memory usage, too.  All three branches were run in newly
 created EC2 instances.  I can't spot any difference between the branches.

 > Also, can you attach the performance graphs for this set of runs?

 I didn't make any performance graphs yet.  Making them now.  Will attach
 them once I have them.
