The default of 16 connections is IMO too many.  The HTTP spec says that a 
single user client should not use more than two persistent ones per server 
(which on the other hand is somewhat modest these days, mainstream browsers 
limit it to 6 or so I think), and yum's downloads don't come from many 
different servers that often.  I'd imagine that something like 4 would be more 
appropriate default.  Even better if there would be two max limits, a global 
one across all servers in the download batch, and a per-server one.
