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

[George Byrkit]

Ken,
I think that you misread Hermann's email.  He said that he was using 'Gigabit Ethernet',
which is NOT 100BT Lan.  It's 1000BT Lan.

Where did you read or infer '100BT'?

It's a bit early to wonder about Windows 8 network optimization, I think.  Code isn't
frozen.  And Windows 8 is much like Windows 7 with regard to the networking, if I recall
correctly.  And remember that PowerSDR and KISS will NOT work on the ARM tablets for
several reasons: the ARM tablets ONLY support the pesky new 'Metro' apps, and PowerSDR and
KISS are NOT those, and likely ONLY Metis/Hermes would work there, as you'd need ARM
device drivers for LibUSB0, and I'm not sure that they are going to exist.  I think that
porting PowerSDR and KISS to 'metro' is a long ways off, if ever.  There are many
programmers who think that Metro is only a 'tablet' or phone (touch-screen) interface, and
that trying to foist it off on the desktop could be the end of Microsoft, a worse fiasco
than Vista was.

Hello OpenHPSDR TCP/IP users,
has anyone acquired a tool or knowledge about how
to optimize Windows-7 (and Windows-8) TCP/IP performance
for the new Hermes (or Metis) connection?

I looked with Google and there is a bewildering amount
of information, that is all very old. I find that there
are many Linux TCP/IP settings and variations for large
packets and so on.... but how does that relate to the
Metis or new Hermes PHY and FPGA code from VK6APH?

Hermann's latest 7 channel demo achieved a reported
72Mbps across his 100BT LAN. That is truly remarkable.
What is your experience with Metis or multiple Mercury
boards?

thank you for your discussion and information,
73 de Ken N9VV
