Intriguing! It looks like upload typically took about 150 seconds and
download took at least 850! Upload has pipelining [1] and download
doesn't [2]. I wonder if that could account for *all* of that large
difference!
This is issue #1110. It would probably make an excellent first hack
for a new Tahoe-LAFS coder in the v1.9 timeframe. :-)
