I did a test with a laptop (XP sp2 512Mbram 1.7GHz single core no HT)
which is similar to the OP systems and I saw the network test issue.
The SB and laptop are wired through a switch so minimal router issues
and no wireless.
Without pipelining enabled - network test was consiustent only 94-96%
This afternoon - for the first time since my last post - while playing
music the SB started to stutter.
Went to the PC where my nugget was using the CBEEBIES website. Closed
firefox, and SB3 was fine... A few minutes later I let him back on and
within seconds the mini-equaliser on the right hand

It's definately nothing to do with traffic!
In the logs over say 10-20 second periods I can see no communication

A couple of points.
1. If network traffic is between a PC app and 127.0.0.1 or the server
IP address and the App is on the same PC - it will not show up with

show.

512Mb is no way enough to run XP IME.

First try to get a feel of what is happening such as

2. Look at the GMAIL traffic - are the packets very big or very often
compared to other traffic.
3. Have a look at selected GMAIL packets - use top panel to select a
packet and look in bottom panel
AFAICT The only traffic on those screen are to/from SB3 - you can tell
by the port number 3483 is either source or destination.
The dark lines are retransmission - it's not clear why
