In this case the lag is a side effect of LOTRO generating a lot of traffic.

I'd like to see specs from the users that run the game flawlessly.

Also, it might be worth noting that some people might not even notice the extra
traffic. Maybe with some players the amount of generated traffic is less than
on others. Also some people have higher bandwidth capacity than others. With
10/10M bandwidth the lag is rarely noticeable, because the upload peak rarely
gets up to 10M.
--> Higher upstream capacity, less lag.

While playing, could you (and others) run the bw_ping.pl script on some box
that runs the game well? That way we know for sure that the game doesn't
generate extra traffic.

You can run the script like this:
wget http://www.korkalo.fi/bw_ping.pl
chmod +x bw_ping.pl
./bw_ping.pl 195.33.152.173,google.com,`ip route|tail -1|awk '{print
$3}'`,localhost eth0 --interval=2 > /dev/shm/lotro_stats.csv

- Here I am directing statistics to shared memory device, to avoid any extra
I/O load on harddrives.
- 195.33.152.173 is IP of some UK lotro server, you might want to replace that
with the one that you are using. You can find out with wireshark or netstat.
