How big the XML stanzas can be that Openfire can deal with

Hello,everybody.

 In XEP-0065: SOCKS5 Bytestreams,they said "XMPP is designed for sending relatively small chunks of XML between network entities and is not designed for sending binary data".

 In XEP-0134: XMPP Design Guidelines,they said "The core strength of Jabber technologies is the streaming of relatively small XML fragments between presence-aware network endpoints".

 So,I wander,How big the XML stanzas can be that Openfire can deal without performance problem. 1KB? 1MB? or 10MB?

 Thanks.

Openfire limits the messagesize to 1 MB (uncompressed). Larger messages are not allowed and yield to an error. Having plenty of memory one could adjust this to 10 MB but not much further as the messages must be parsed and this happens in-memory. With only 2 clients even 1 GB messages may work.

thank you very much
