I had a similar effect once, when downloading from my cloud site into
my home network, which did happen only in specific conditions when
routing things around a few more hops in the home network.

After experimenting a while with the congestion stuff, it finally
resolved quite differently: TSO offloading on the FreeBSD server in
the cloud needed to be disabled.
