[zeromq-dev] inproc seems to be rather slow

[Brian Knox]

Here are my results:

[laotse at moneta perf]$ ./inproc_lat 1024 100000
message size: 1024 [B]
roundtrip count: 100000
average latency: 13.333 [us]

Try sending more than one message.

I haven't looked at the performance test code but my guess is that it is
measuring some of the test setup time in it's measurements.
