ISTM that it would be better to use kern.hz=100 in this case.
My reasoning is that a web server shouldn't be terribly sensitive to
latency, so it's better to have longer quantums to get more work done
without context switching overhead. If you're not using polling,
you'll be getting interrupts for network traffic anyway.
That what i personally thought. However 100 seems to be too rough.
I just feel so, no reasoning behind this ;)
Maybe 200-300 is better than 100 and better than 1000?
I wonder how to build a test case for this to find best settings for
web server, so others will not stuggle with this on the future.
With polling on however, a high HZ value makes sense.
polling does not make sense in case of webhosting though ;)
