OpenFire HTTP Binding scalability

Hi,

According to http://www.igniterealtime.org/community/blogs/ignite/2007/10/31/openfire-unleash ed, 500k connections can be supported concurrently using only 2 nodes.

But with HTTP binding, unless I am mistaken, there is no longer a persistent connection for each user. Therefore the overall number of users that can be on at once will be much higher, right? Have there been any tests done involving this?

Thanks,

Karthik
