I am sorry. I cannot think that way. :-)
Instead of attempts to scare, better resend original report,
where you said how much performance degraded, I cannot find it.
* I do see get_offset_pmtmr() in top lines of profile. That's scary enough.
* I do not undestand what the hell dhcp needs timestamps for.
* I do not listen any suggestions to screw up tcpdump with a sysctl.
Kernel already implements much better thing then a sysctl.
Do not want timestamps? Fix tcpdump, add an options, submit the
patch to tcpdump maintainers. Not a big deal.
