 I really hope Macports can have two features:

 1 Global master_sites option to override Portfile settings
 I find some sites (esp. sf.net) are very slow. For many ports, I have to
 manually download source tarballs from distfiles.macports.org and then
 rerun port install.

 How about add a global option to allow us to use distfiles.macports.org
 only? It can override master_sites in all Portfiles.

 Since it seems distfiles.macports.org mirror all files, the natural way is
 like this:

 use_main_mirror  yes

 If set, all source tarballs will be downloaded from
 distfiles.macports.org.

 Hope server is robust enough or at least smoke/fire-proof enough.

 2. Use some download acceleration tool like axel
 It can accelerate and resume downloading.

 If combined with above setting, once again I hope server is super robust
 and super smoke/fire-proof.
