Do The OpenFire Requirements Still Hold?

http://www.igniterealtime.org/community/docs/DOC-1543

Does the document stating the requirements for OpenFire still hold or are they greater/less? Because my client is going to be using openfire but the packet/sec rate is going to be extremely high. for example 50k packets/sec. How does this effect the requiremtns for suppose 50k users logged in with a 50k packet/sec rate (Total) .

Thanks,

Faisal
