Concurrent Users for a normal OpenFire Server Deployment

Hi Guys,

I have deployed OpenFire 3.9.1 version on my mac machine. I will soon be using for a chat module in my mobile app. I was interested in some information regarding how many concurrent users/connections can a single normal openfire server deployment handle ? How more users will it be able to cater if i host it on some commercial hosting services like amazon or giga pros?

I am looking for some general numbers that can be of help to me .

Thanks.
