A and B send msg to C with multithread.how do the openfire handle with the msg?

A and B send the msg to C with multithread。 the openfire will handle the msg one by one or use multithread?and the C call the IQprovider is one by one or multithread?

I’m unsure what you’re asking exactly. Openfire will always process incoming message stanzas individually, not in context of a larger conversation. I hope this helps.
