Title: Minor(?) detail with OPNsense 25.1.1 and setting " vm.numa.disabled"
Post by: Gary7 on February 20, 2025, 02:47:42 AM
OPNsense 24.7.5
This update also disables NUMA by default which can bring a boost in network throughput on affected systems. 
system: default to vm.numa.disabled=1


OPNsense 25.1.1
execute: sysctl vm.numa.disabled and the value is vm.numa.disabled: 0
I've added "vm.numa.disabled" to Tunables and verified that vm.numa.disabled="1" is in /boot/loader.conf
After reboot, the value is still vm.numa.disabled: 0

Since I have an APU2D4, I would like to explicitly disable NUMA.
Am I missing something?

An APU2D4 does not have NUMA, so there's nothing to disable.

Setting correct sysctl/tunable policies across all hardware is so hard to pull off without noise like this.

Functionally, it's fine.


Sorry,
Franco

Thank you for the clarification. I didn't know if the setting had any effect on a non-NUMA CPU.
I apologize for the noise.

No worries, these reports are very much appreciated. When numa isn't attached the sysctl isn't attached either so it simply complains about that.


Cheers,
Franco
