Openfire Limitations

Hello. Could you inform about following openfire limitations (our version 3.6.4)

  1. How many connections allows from one (same) IP address? My tests shows that only 72 XMPP connections allowed from same IP and next are blocked. Am I right? How to increase this value?

  2. What maximum size of XMPP custom data request allowed via custom data? I note that some big messages reject by Openfire and TCP connection broken.

  3. What maximum speed for XMPP connection from same IP? How to increase this value?

  4. What maximum speed for sending XMPP messages? How to increase this value?
