[zeromq-dev] IPC vs TCP efficiency

[Tonis Xie]

Hello,

I have made a test on PUB/SUB pattern to compare the communication
efficiency between IPC and TCP. While IPC was supposed to be better, it
turned out that TCP is more efficient and stable than IPC.

Could anyone explain why, or did I use it in a wrong way?

Attached are two files that were modified based on ZGuide example "weather
updater". To make the empty loop work, I used gcc -O0 to compile the code.
