Hi there, sorry for the ignorance, but which are the best settings for
sysctl?
I guess, it depends on the workload that one is executing, right? But
based on the emails, I understand some basic ones can be applied to help
with general applications, am I right?
If that's the case, can we

There is a lot to say here.
One has to
I can say that these "micro" benchmarks are not "so much" useful .
When such comparisons are made based on "abstract" views , they
DO NOT SHOW very much utility .
Over previous years I am always stressing that proper comparisons would be
based on a "specified" workload : Which distributions
Maybe FreeBSD wouldn't win but results would be much closer. It's also
known that default compiler options for ports aren't best. Default
sysctl.conf default settings aren't best. They could at least compile all
the benchmarks with the same compiler features. So -ffast-math, -flto and
-O3 + code

Hi,
Is there any tunibg guide(s) to make the default not conservative in a
regrding to several use cases like using as web server?
- FreeBSD Handbook, Chapter 12. Configuration and Tuning
- section 12.12. Tuning with sysctl(8)
Just to be clear I almost not used linux and always freebsd
Hi,
I see these claims over and over.
So I must ask.

I know there are few network (aka routing / forwarding) guides.. but maybe

I am surprised to see that the BSD cluster today has much worse performance

What do you think of this?
"Default" FreeBSD install setting are quite conservative.
The Linux common distros are high tuned, those benchmark is in my
opinion comparison of apples and oranges.
