What - ftp.netbsd.org or cvs.netbsd.org?

I can ftp from ftp.netbsd.org at a rate of about 150 to 180 kB/s, depending
on the client machine/location, with v6, v4 is actually 15% slower
125 kBytes/s).

I didn't check cvs.netbsd.org, but use it regularly, and afaik mostly
over IPv6.

I'd guess broken path mtu detection.
