I just tested Debian's 2.6.38-1 kernel, and it has the same problem,
though I just noticed something potentially interesting.

Right after booting the system, I started a wget which ran at a steady
800+K/s.  Then I started an "lftp get -c" to grab a kernel image, and
both connections settled at about 400K/s.

After a minute or so, I killed the ftp connection; from then on all
transfers were limited to 60K/s.

Now that I think about it, that's consistent with what I've seen up to
this point.

Hope this helps
