Comment (by aggraef@…):

 Replying to [comment:7 cal@…]:
 > Have you looked into IPv4 vs. IPv6? Your speedtest might use IPv4 and be
 perfectly fine while the download from the macports mirror uses IPv6 and
 is slow (e.g., via a tunnel or something; Windows machines have been known
 to advertise their Toredo tunnels on local networks, causing problems like
 these).

 There's no Windows server on my network, and the network preferences on
 the Mac show nothing unusual (cf.
 https://www.dropbox.com/s/i1e2vn4iasuw873/Screenshot%202014-10-12%2014.37.48.png?dl=0).
 IPv6 is set to automatic and both IPv4 and IPv6 addresses seem to be
 configured all right through DHCP.

 Can anyone suggest a way to check whether the connection actually goes
 through IPv4 or IPv6? I must admit that I don't know how to do this.

 One weird thing I noticed now is that the download rate seems to depend on
 which file I'm trying to download. With
 http://nue.de.packages.macports.org/macports/packages/gtk3/gtk3-3.10.0_0+x11.darwin_10.x86_64.tbz2
 it soon drops down to a crawl, while with the file you tried it works ok
 (not blazingly fast, but workable).

 Again, this is reproducible for me. Can't be the disk on the Mac which is
 an SSD. Could it be that there is some slow or faulty harddisk on the
 servers there?
