I am working on a stocks quotation system as a server. A message <= 400bytes will send 10 - 20 messages/sec, which i consider is huge ^^. My server also needs to keep watching on each session (500 - 1000each server) and send the data to the session who registered this symbol.(BTW, right now I use HashMap to store the session, sessionID, I don't know if it is the correct way and I use Session.hashcode as sessionID).
