Adding the last two options of my setup increased the upload rate by
about 2MB/s, with peaks totaling to 20MB/s. The download rate has not
been effected however.
I went from 7.5MB/s up to 9.3MB/s on a 100FD connection just by adding
that same last 2 options, I only had "socket options = IPTOS_LOWDELAY
TCP_NODELAY"
Thanks Rich!

I am using -CURRENT here, disabling net.inet.tcp.inflight improves the
download rate by 2MB/s!
How old is that CURRENT? I believe that shouldn't happen after Andre's
commit back in March.
I can't see any difference toggling inflight on or off.
