I've had a look at System : Settings : Tunables the other day and noticed a lot of tunables set to non-default values.
I am pretty sure it was not me setting those tunables.
So I "reset all tunables to default" with the second of the two trashcan buttons, applied, rebooted.
Alas, all the non-default tunables remained in their non-default setting.
Can the "Default" column in the table really be trusted?
Or does the "reset to default" button just do nothing?
Edit: Or should I select all lines in the table and delete them (with the left trashcan button "delete selected") to reset to default values?
What is the difference between "delete selected" (after selecting all) and "reset all tunables to default"?
OPNsense 26.1.4-amd64
I'm not sure we have the concept straight here: the tunables are in the configuration and they are applied to the system. Some have defaults others not. It would be good to check on a sample you can list tunables with "sysctl -a" on the command line. Relatively sure the values set match the command output.
Cheers,

Are the listed defaults those of the kernel or are they opnsense config defaults?
