An Intel Celeron N5105, on one core, does ~28Gbps locally between two bridged interfaces with iperf.
A Raspberry Pi 4 has a single PCIe lane with a total of 4Gbps bandwith for everything (all USB ports and Ethernet).
Edit: shameless plug, but I just finished writing an article on my new home network, including the router with the above spec/results: https://atodorov.me/2024/07/03/running-a-multi-gig-home-network-in-2024/ https://atodorov.me/2024/07/03/running-a-multi-gig-home-netw...
- Asmod4n 2y agoThe CPU is the bottleneck. All switching is done in software with off the shelf NICs.
- sofixa 2y agoYes, my Intel Celeron N5105 had a full core pegged at 100% while doing that iperf and getting those numbers. But there are 4 whole cores, meaning I can get far more traffic switched and routed with the CPU capacity than all the ports combined can sustain.
