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) http://osdl.org/lab_activities/kernel_testing/stp/ -- Stephen Hemminger <[EMAIL PROTECTED]> - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
