  The problem is, there is *NO* appropriate flow control the switch
can implement.  If you don't use Ethernet flow control, data doesn't
transfer well.  If you do use Ethernet flow control, data doesn't
transfer well.

 As DTVZ points out, the only way to solve this problem is to tune
your network stack at higher levels, such as the IP layer or the
application layer.  The chief problem with this is that you have to
tune with knowledge of the specific characteristics of the network
you're on.  And if you've got multiple networks (like, say, the
Internet) which demand different tunings, you're never going to get
optimum performance out of all of them at once.

  One could change one's LAN hardware to something with more
intelligence than Ethernet, of course.  But that tends to be hideously
expensive.

  We live in an imperfect world.
