Paul,
That was an excellent idea indeed. As i was simply following the first
example in the guide and developed on top of it, i did not read the api.
After going over the socket API, now, instead of how many messages can a
pub send in a second, i record, how many messages can a consumer get in one
second.
This brought down the number considerably from 4.5GB/sec to 1.5Gb/sec.
But its still a mystery, how can i get a number of 1.5Gb over 1Gb network ?
