Tunables Section

[spetrillo]

Is there anything here that I should be using on a default basis?

Can you rephrase your question? I'm not sure what you are asking.

Sorry if I was not clear...

I am merely asking if there are any tunables that make sense to use by default, where I would believe most are used in specialized cases?

[hushcoden]

I'd start with those ones: https://teklager.se/en/knowledge-base/opnsense-performance-optimization/

Most on/off defaults are set for specific use cases and should be changed with care.

Buffer size based defaults can be tweaked and a lot of those exist like hushcoden suggested.


Cheers,

I am curious to understand more about the following changes:

hw.igb.rxd="2048"
hw.igb.txd="2048"
net.link.ifqmaxlen="4096"

I am noticing that memory usage went up dramatically when I implemented these. Is this ok? I have Intel i210-AT NICs.
