Going with what alpharabbit said: you may be vastly overestimating the amount of traffic you’ll receive (unless they start uploading test data again).
Like this guy has 130’ish nodes. And if we look at his Weekly traffic graphs the average ingress is 350’ish Mbps, and egress is 150’ish Mbps. If you squint at it a bit… that’s around ±2.7Mbps inbound and ±1Mbps outbound averaged per node. And he’s on a 10G connection.
So… tuning your 1000Mbps connection may not add much 
True, things will burst higher. And true, we’re around three months into a low-traffic period. So thing will hopefully pick up soon…
(Also: I just noticed you made a couple performance-tuning posts recently: so remember any answers here aren’t meant to be discouraging. It’s just other SNOs saying what traffic they’ve been seeing)
