Mine I set to 100Mbit when the new system kicked in. I think that's the pool "doing it's job". Before I would get very large spikes of 40k+ clients and "storms" of packets and such. Since the new one I see a pretty consistent 6k clients (esitimated of course). Packet rate seems to be around 15 packets/sec with lots of smaller peaks in traffic that usually get smoothed out in the number of active clients
http://rikku.vrillusions.com/ntp/ I'll probably end up stopping the active client monitoring. It's one of those things that's impressive (LOOK 6 THOUSAND PEOPLE ARE USING MY SERVER!!!) the load it puts on the server having a tcpdump running 24/7 doesn't seem worth it when the packet count is reported directly from ntpd and is definite (the server can easily count how many requests it's receiving and sending). Also, even turning up the netspeed could take a while before your averages start to go up. When I upped mine to 100mbit it took a few weeks for it to stable out at around 6k clients or 15req/sec like it's at now. As you are added to the pool more and more often it will probably go up eventually.
