jeromq::push very slow with zmq3::pull

[sixtus]

Using default options, zmq3 is about 1/10th the speed of jeromq::pull or c::pull.

I am running out of ideas how to explain this:

I have a producer using jeromq to push messages.

All consumers are NOP for now, they just pull the messages.

It works fine for clients written in jeromq and the provided benchmarking tool written in c.

However, if I connect using zmq3 the producer starts to stall as it dead locks on send. The go process is more or less idle.

Any ideas?

I have no clue.
