Since there are only five interfaces on the system, it likely doesn't 
make much of a difference in your specific benchmark but the 
top-of-trunk version of sudo has the fix/enhancement to allow one to 
tell it via sudo.conf to not grab the list of interfaces on the system.

Might be worthwhile though to take the interface count out to 2000 or 
more in the name of doing things at scale.  Namespace count as well.

happy benchmarking,
