What are you running on the router?

if you don't know, then why are you answering?)
we could also ask if the router is doing something else than being a router.
if yes, what ?

Omg, nevemind. There must be some language barrier. Perhaps someone else can chime in.
The setting relates to service on YOUR router. We can't guess what you're running that needs the setting (if anything).
Then you refuse to answer - so we cannot assist you.
just a router, adblock, dns-https
what services specifically is this setting intended for?

I'd be rather worried if you didn't know 
i understood this myself, but there are many services and ?
As the self-manual says on the screen:
It directs streams of packages to certain processors
Hence we asked you what's running on the router that does so.
Are you using your router as a streaming box?
Are you streaming music from your OpenWrt?
well yeah, just a regular router for the internet

then leave the setting as it is, something you were told to do 2hrs ago 
i suspected from the very beginning that it would be better not to touch this setting, but I decided to ask just in case

"if it works, don't mess with it..."
anyway, i realized that this setting is for some nonsense that i don't use

No shit!
thanks for the answers, but no one really explained what this setting is for with an example)
i write through a translator, so it doesn't always convey the idea correctly
Example:
Enable if you're running streaming software.
data transport optimization, read for instance https://docs.redhat.com/en/documentation/red_hat_enterprise_linux/6/html/performance_tuning_guide/network-rps#network-rps or https://docs.kernel.org/networking/scaling.html, even though it refers to NICs.

like an iptv player if installed on a router?

here on the forum, a person wrote that he tweaked this setting for Wi-Fi
but I doubted the correctness of his experiments
but he wrote a lot and claimed that the setting supposedly helps
For network devices with single transmit queues, best performance can be achieved by configuring RPS to use CPUs in the same memory domain. On non-NUMA systems, this means that all available CPUs can be used. If the network interrupt rate is extremely high, excluding the CPU that handles network interrupts may also improve performance.
Well, as I understand it, this is a useful function and can be turned on at 128, or am I wrong?
