Network Guide Streams (RPS)

So look here:
https://www.kernel.org/doc/Documentation/networking/scaling.txt
and here (on your OpenWrt 24.10.0-rc07 router)
/usr/libexec/network/packet-steering.uc
where your parameter of interest is called local_flows and sets the rps_flow_cnt parameter and that is used for RFS receive flow steering...

I would guess for a normal router leaving that disabled is just fine, but by all means test it and report back.

read the help text again ...

Note: this setting is for local services on the device only (not for forwarding).

but if you got time to kill, knock yourself out, and report back.
