It basically depends on the RAM. On an AWS large instance it can reach 10k
concurrent connections, with roughly 10k messages/second.

I did this testing some time ago, so these figures might have changed.

the performance of offline messaging mainly depends on the used database. With LevelDB there is almost no performance overhead.

Have a look at: http://mcollina.github.io/mqtt_and_nodejs/#14
