Achieving sustained 25Gbps throughput

[VRBitman]

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.
