I'm getting about ~800-900 Mbps down and ~15 up (a bit more than what I pay for). I did notice that when I saturate the sownly speeds, my CPU will max out and I'll start getting latency spikes to the point where the traffic stops on the network.
After looking into it and adding a buffer bloat rule/ limiter, I'm not having any issues. I guess that's the price of running IDS on 7 VLAN interfaces, but it's getting by. When I go 10Gbe I will definitely pick something a little more capable, but it's great for 1 Gbe
