[zeromq-dev] large numbers of PUSHers?

First, thanks to Pieter for his overnight response to my first Q ("set socket opts before bind/connect!") on this list, much appreciated. And thanks/grats/props etc to the team who has built ZeroMQ.. I'm new to the space but been round long enough to know when to be impressed. That said, I want to

[zeromq-dev] NetMQ: is PUB/SUB filtering done at publisher side?

Hello everybody, I'm working to my first ZeroMQ based real-world application and I have a few questions: 1) I'm working on .NET and I choosed NetMQ instead of CLRZMQ just on the base of github activity. I've noted there are some differences between the two API (for example I had to Subscribe("") i

I have the same results with the Python examples. So the problem does not originate in my C/C++ build chain : OK if client & server are in the same console, fails in two different consoles. Le 26/06/2013 15:06, Laurent Alebarde a écrit : Hi list, I cannot manage to have my code working. It s

Hi list, I cannot manage to have my code working. It seems that I am sticked in zmq_poll. Even in an infinite while, a printf and a 100 ms time-out, the printf executes only once, so I conclude that in my code, zmq_poll blocks internally. So I have tried the examples - precisely flclient1 al
