If I tweak the #sysctl.conf file on the #host, physical machine, does this means that the virtual machines will benefit from [most] of the tweaks?
I think that, being this true, only certain tweaks like #wmem and #rmem are in a per-machine basis. Is that correct?

Eu não preciso fazer tweaks no #sysctl de cada máquina virtual se eu aplicar esses parâmetros no sysctl da máquina física #host, né?
No máximo talvez o #rmem, #wmem, mas de resto, se o host está otimizado, as máquinas virtuais também estarão. Correto?
#proxmox #sysctl #host #rmem #wmem

hw.perfpolicy=manual
hw.setperf=99
in sysctl.conf was enough to keep the kernel from forcing the CPU into "turbo" mode and it has been rock solid for a week now. Crashing 2-5 times per day before hand.
Just happened across this little tidbit:

Of course, the fact that my hardware is ancient probably contributed to the problem.

- unencrypted #GCP service account keys

If nothing else, I hope the queries are useful ideas for others! Have a great weekend. 🌴

#FreeBSD improved sysctlbyname() to handle:
* a name with an empty string level, example “security.jail.param.allow.mount.”

sysctlinfo improvement:
~100% more efficient than the kern_sysctl.c undocumented interface to explore the MIB and to pass all object info to userspace
