When I did the port randomization patch the benchmark that was most impacted
was LMBENCH. The biggest change was in the communications latency results.

If you want, you can sign up for a free access to OSDL test machines
and use STP to run lmbench and easily get before/after results.

1. Go to osdl.org and get associate account http://osdl.org/join_form

2. Submit patch to Patch Lifecycle Manager http://osdl.org/plm-cgi/plm

3. Choose test to run Scalable Test Platform (STP)
