Re: dragonfly file transfer rates...

    Even with a cheap machine maxing out a 100BaseT network should be
    easy.  The issue with the above tests should simply be a matter of
    adjusting the TCP options (e.g. in Apache on the sever) and/or client
    to use a somewhat larger TCP buffer.  Apache servers typically default to
    tiny TCP buffers out of the box.  You shouldn't need more then
    a 32KB TCP buffer on the client and server to max-out 100BaseT.

    Presumably, also, the server's hard disk is faster then the transfer
    rate.  If it is a modern hard disk it ought to be able to read in the
    30-60MBytes/sec range.  Old HDs tend to operate in the 5-20 MBytes/sec
    range.

    Tests are only useful if you know why you are getting the results you
    are getting.  Simply running a test without researching the issues is
    not going to give any meaningful results.
