Tests on Linux Real-Time Kernel

http://www.zeromq.org/results:rt-tests-v031

Conclusion: "Our tests prove that the real-time Linux kernel, specifically, SUSE Linux Enterprise Real Time 10 SP2, is capable of eliminating latency spikes. It is expected that our results would be even more favourable for the real-time Linux kernel if these tests were run on boxes loaded with other tasks, rather than on a clean and idle test environment."
