Thanks.  Back in the modem days, baud was (correctly) shorthand for
bps.  Wikipedia states that is no longer valid.

Rough conversion (from the old days) was:
1 byte of data
= 8 bits on disk
= 10 bits of network traffic
= 13 bits of encrypted (SSL) network traffic
Data compression can reduce the traffic up to 50%.

Maintaining 800 MB per second without compression may completely fill
a gigabit network connection.  The OP would want a second network
connection to avoid running at full capacity and handle spikes.
