Something is not adding up. 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
