Not much else going on with the system.

Exiting my VNC session does not impact the BW I see.

With Chrome trying to connect, the results look similar.

 

Oh well.  I could try a clean install, I guess.

I isolated my network to just the RPi and my Computer and still only get
2.8K/s.

I had this working fine in June, but not so much today.

The setup is mostly like what is outlined here:

Things look fine on the RPi side (the date is wrong):

I can use wget on my desktop computer (win7-64) and see the connection and a
trickle of data:

$ wget 192.168.0.3:8081

Nothing shows up when I try to connect with Chrome.

I am thinking the issue is with the 2.9K/s data transfer rate.
