I'm despondent. I took my courage in both hands and upgraded the kernel to 2.6.31.7 from the unstable repo but see no discernible improvement in network performance. I'll have to see what happens with other hardware on the same switch.

Where the 2,5MB/s limit is due to the CPU load of SSH, it improves a bit using a difference cipher.
$ scp bubba:big_file .
... 2.9MB/s
$ scp -c arcfour bubba:big_file .
... 3.9MB/s

if you want to measure network speed, use wget, not ssh or scp

Would I be right in guessing that the faster CPU in the B3 has fixed this problem for those who have upgraded?

You would. It made a tremendous improvement.
The "average load" as reported by top and uptime tended to go above 2 when there was traffic on the Bubba 2, and it never even came close the gigabit LAN theoretical speed, nor the 100 megabit theoretical WAN speed.
Transfer speed and user experience has improved a lot since my Bubba 2 was replaced with the B3.

Great! That's settled then...
Thanks.
