Hi all,
looking to put together a mini PC that can sustain a 25Gbps throughput.
My CPU is an i9, I'm fairly confident that has adequate horsepower.
What about RAM?
The official hardware sizing guide of OPNsense states that to handle a throughput of over 750Mbps the "recommended spec" is needed.
And the recommended spec indicates 8GB of RAM.
But is that enough for 25Gbps or will it handle just a little over 750Mbps?
I don't expect to have many sessions going on at any given moment.
I live alone and I generally use only one device to surf the Internet.

Maybe the guide assumes that above a certain throughput you are probably pushing lots of states or have some number of users/services/aliases/IDP etc.? It may or may not be the case depending on your particular network.
I might learn something new here but I'm tempted to say that as long as you have
enough RAM for your needs (and some buffer) then the throughput shouldn't be a function of the amount of RAM. It's probably more affected by the RAM spec, CPU, PCIe lane configuration, etc. Just my assumption.

At 25Gb/s? That's some surfing.

In VR apparently and you know what that means... LOL! ^_^

For sure he lives in Switzerland, with init7 it's the same price for 1, 10 or 25Gb/s

Well I download things every now and then as well.. maybe a game on Steam, an ISO somewhere else..

Yes I can confirm that.
And I've received confirmation somewhere else that RAM is not important for achieving very high speeds.
Thank you everyone.
1st build a router and test speeds across interfaces. If you can build the 25Gb links.
After that, then you can install FW software.

If you don't mind saying, what hardware precisely (I believe the first "i9" was a Kaby Lake and the last a Raptor Lake)? Also, NIC and RAM.
