[hpsdr] optimizing my PC for TCP/IP to Hermes/Metix?

[Ken N9VV]

Thank you George. Yes I misunderstood that Hermann was using a 100BT
LAN. I have a Gigabit switch here and my mITX (Atom 330) says it
is connecting at that high speed. But my poor old dual-core Dell
needs a new Gigabit LAN PCI card!

I thank you very much for your comments about Win-8. I simply will not
worry about it. My fear was that Hams would purchase the new Hermes and
then at Christmas time they would purchase a new i5 or i7 PC and it 
would be delivered with Win-8 installed on it :-(

I am approaching this from a "Customer Support Tech" point of view :-)
and I wanted to have a clear understanding about what utilities and
potential optimizations we can offer to our happy and excited new
owners :-)

many thanks George,
73 Ken
