A while ago, I noticed someone's kernel config that included:
hertz=2000 which made me wonder where this setting info comes from?
I've been using hertz=1000 however, with my much faster boxes, is this
appropriate now?
It depends on what you are doing: it is most useful to tune HZ higher when
machines are being used as firewalls/routers and/or are using device polling.
Faster HZ rates cause greater system overhead but will give shorter latency,
up to a limiting point.
In simpler words, tuning HZ too high is bad. :-)
One needs to do measurements and tune appropriately.
