Hello the following post has been published in 2008. And back then the Openfire server had the following hardware requirements per quota of concurrent users.
At least 384 MB of available RAM and one 1.5 GHz processor.
At least 768 MB of available RAM and one 3.0 GHz processor.
At least 1.5 GB of available RAM, two 3 GHz processors, and one connection manager on the same machine.
At least 2.0 GB of available RAM, two 3 GHz processors, and between 1 and 4 connection managers based on exact size, each on their own equivalent machine.
However, from 2008 to 2014 almost 6 years, I would like to know if the requirements can be applied to Openfire 3.9.3 or had they been improved ?
The other question is about the usage of a connection manager for concurrent users from 25,000 - 100,000.
I haven’t seen a lot of posts about it recently; Knowing that recent openfire releases had gotten better and better handling more users, I would like to know if the connection manager is still necessary to use ?
