I’m working on a large scale mobile chat app similar to Whatsapp and I have following questions:
1- I’m just wondering if Openfire is capable of handeling 1 to 10M users or not?
2- On average how many users each node can handle and what secification is required (RAM, CPU, etc)?
3- With hazelcast clustring how many nodes can we have?
4- Should I use Openfire for large scale userbase or I should look ingo Tigase or Ejabberd?
Looking forward to hearing form experts here.
