What is the recommended maximum user count for a single, non-clustered, server running Openfire using Spark clients? This would be on a VMWare virtual server, so I could allocate any resources necessary. I am just trying to figure out if Openfire/Spark is even a viable solution for my company and if so, how many servers I will need and if I need to go to a clustered architecture. I have about 1000 users that will need to go on this.
Thanks!
