This got mentioned on freebsd-security as a possible tweak to improve the
performance of an ipfw firewall using dummynet pipes:

And I've seen other references to increasing the HZ value in order to
increase performance with respect to certain network functions.


Exactly what does increasing the HZ value do, and what drawbacks might it
have?
