      #49452: rsync.macports.org is very slow

-------------------------+--------------------------------
 I installed MacPorts 2.3.4 using the official pkg installer on OS X
 10.11.1 (first on Saturday, and now again, to try to figure out why it
 takes 52 minutes on my Mac Mini "late 2009").  The last 30 minutes of that
 time are spent by tclsh building the PortIndex, already reported as bug
 #49050.  The first 20 minutes seem to be just the rsync-ing of base.tar
 and ports.tar, with a transfer rate jumping between 14KB/s and 33KB/s, as
 seen in Activity Monitor.

 To make sure this isn't due to a regression in El Capitan, I tried rsync-
 ing base.tar manually from my Fedora netbook, and compared the main
 server, rsync.macports.org, with the French mirror (I'm in Germany):

 This is your local MacPorts mirror.

 You may sync whenever and how often you want,
   but keep in mind, that we enforce a maximum of 5 (five)
   concurrent connections per host. If you feel this is too little,
   please contact the administration.

 The server is physically located in Roubaix, France
   and hosted by OVH. It though features a German RIPE failover IP.

 If any problems or questions arise, please contact
   Mihai Moldovan <ionic@ionic.de>, Karlsruhe, Germany (primary) or
   Joerg Hoffmann <jh2000@root24.eu>, Nordholz, Germany.

 Is rsync.macports.org intentionally limiting its bandwidth for clients
 outside the USA? Unfortunately, I didn't see any option of selecting a
 different mirror in the pkg installer.
