Traffic is probably not the problem. Many rooms with many users make
much traffic. Presence probes every 5 minutes make negligible traffic
compared to the chat traffic. independent of the number of users it is
always a very small share. Only the weird case with many many users, who
enter, stay for long and do not chat sees a significant traffic increase
by probes. But it is still small in abaolute terms.
