from my brief search:

real-world OPNsense (yea, that's not Debian) benchmarks show that even low-power Xeon-D (Skylake-D SoC) with 10G SFP+ NICs:

pushed 9.40 Gbps in plain router mode

7 Gbps with packet filtering and no rules

7 Gbps in NAT mode

5.5 Gbps with a default ruleset

Using a Xeon for a router just because you want to use linux is a wild choice.

I’ve been running a Supermicro X10SLH-LN6TF as my router, and it’s very well suited for the job. Power use is very high for a home router, but reasonable for a 1U router - especially considering the era it’s from and its capabilities (routing 5-8Gbps per stream depending on firewall config, able to handle a couple active streams, and line rate routing with no firewall).

I wouldn’t suggest anyone buy something like this today for home use, but 6 years ago when I purchased it there were not many 10GbE routers to be had period, let alone for the price ($300 roughly if I remember correctly ). Even considering the cost of power over the last 6 years, I still come out much cheaper than if I’d bought something more power efficient new at the time.

		FWIW, I got 10 Gbit at home 2 years ago and built my router for $100 using a ThinkCentre M720q Tiny running on a Core i3-8100T (a mini-PC from 2019). It draws around 15W idle, going up to 30W at full bore. For comparison, the 10G rental router from the ISP drew 15W no matter what (idle or full bore routing). This is with a 10GBase-T SFP+ which probably influences the power draw vs using a DAC. It has no issues maxing out at 9.4 Gbit routing with a single or multiple streams of iperf3 with your basic IPv4 NAT+some port forwards config.
