I did the same kind of thing as last week, with the following changes:
	- Used 0.7Alpha3-rc1
	- Traced a first-time publish of a small share -- should be data- 
intensive due to all the uploading
	- Correlated the twisted.log file to the TCPDump output to see what  
was attempted in each connection
	- Drew some colorful graphs (ooh, pretty) for visualization

See updated: http://wiki.osafoundation.org/bin/view/Journal/ 
PublishConnectionAnalysis.

Really quick summary: the lowest hanging fruit here is reusing  
connections, avoiding actions that make the server drop connections  
(or having the server not drop connections by fixing the 501 response  
bug), and finding out what's going on while the TCP connection is  
live but the SSL handshake isn't started yet (a total of 7.5 seconds  
spent in this state).
