You may want to datestamp the version of HEAD you're using in each test
(assuming it changes between tests). Among other things, I set
net.isr.direct=1 as the default a day or two ago, which will affect a broad
range of performance characteristics. There have also been VLAN tagging
related performance improvements made in HEAD that aren't present in RELENG_6,
avoiding extra memory allocations and frees in storing the tags.
