I anticipate access to a multi-socket numa system in the next few days. Until then a couple of questions: 1. do you take patches to run your tests? 2. do you have a wiki/web page with all of the tests run? I'd like to know what other networking tests have been run. Only this one was flagged, so I presume it means other tests did not hit the threshold. I would like to know what other tests are run. Thanks, David
