ipc-bench
=========

Some very crude IPC benchmarks.

ping-pong latency benchmarks:
* pipes
* unix domain sockets
* tcp sockets

throughput benchmarks:
* pipes
* named pipes
* unix doamin sockets
* tcp sockets
* message queues

one way latency benchmarks:
* shm

The shared memory benchmark is a kind of "control". If run under a
real-time OS it will give you the intra core communication
latency.

ipc_bench.py
=============
requirements:
 - gcc
 - make
 - tar 
 - pyhton 2.7

 ** in order to run ipc_bench.py you have to run "make all" first. **

features:
 - gnuplot output

examples:

./ipc_bench.py --all
