> g: 1gb across 30 IO threads means 1 IO thread can only do 33MB it means as
a user I have to create multiple connections and hope it will be served by
other IO thread to get higher throughput.
A couple of notes:
* You won't get higher throughput after a certain amount of memory (eg:
30MB)
* If you have 16 cores available, you would also have >> 1GB of direct mem
Finally, the number of messages/s is not a good proxy measure for the amount
of memory required in the broker
