Sizing

Hello,

I am looking at deploying an Openfire server cluster with a clustered MySQL server as a backend. I am looking at hosting this in on virtual Linux servers.

Are there sizing tools to help estimate the resources that would be required to support a specific configuration?

Question 1

If all of the servers had the 1GB of RAM, and one CPU. How many users could I service?

Question 2

What would the specs be for the Openfire servers if I wanted to have 10,000, 100,000 and 1,000,000 users?

Cheers,

Cameron
