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 attempt to list them? I am happy to create a
list, document and categorize them based on workloads, I believe it will
be a good starting point for normal users (like me).
I do have a small list of sysctls that I usually apply, but they are all
mostly related to networking and particular to our client's setup.
Best regards.

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 hardening features, for all tested systems. It's also
professional to mention the compiler used (I recall that the previous
Phroenix "benchmark" was done using GCC on FreeBSD which I'll not even
comment).
I could go on with all mistakes made in this "benchmark", but well, I know
- benchmarking is hard.

1. Where are compiler options for BSDs?
2. Why they compare -O2 to -O3 code in some benchmarks? Why they enable
fast math in some, and disable it for others?
3. Why they don't mention powerd setup for FreeBSD? By default it may use
slowest CPU mode. Did they even load cpufreq kernel module?
4. Did they even care about default FreeBSD mitigations (via sysctl)
enabled, or it's only valid for Linuxes? ;)
5. What happened to security and environment details of BSDs?
It's kinda known that guys from Phroenix lack basic knowledge of how to
do
proper performance testing and lack basic knowledge about BSD systems.
Nothing new. Would take these results with a grain of salt.
It is very simple - they are comparing OSes with setting they are
shipped. Average users don't know about tuning so the benchmark is
reflecting what many average users get.
And to be honest - I don't think FreeBSD will win even with everything
best tuned.
Kind regards
