tuned

Solution to Permission denied to /etc/mtab

I was setting up a hypervisor for RHEV running a full RHEL6 install instead of RHEV-H, and I wanted to tune it for better hypervisorness.

So I thought, Hey! I'll install tuned, since I am all excited about tuned after viewing the slides from Mark Wagner's Achieving Top Network Performance (PDF) at the 2012 Red Hat Summit. I was particularly excited about slide 12 entitled "Teaser 3 - latency."
