I took the plunge and bought a Pi 5 to test its routing performance. If it was disappointing, I had 15 days to return it to the shop.
Here’s the setup:The fiber connection is 1 Gbps.
Speedtest results:Even with limited NIC offloading capabilities, the Pi 5 performed quite well! So, I’ve decided to keep it as my router.
Once I get a second computer, I'll place it on a separate VLAN and use iperf3 to measure the throughput between the two machines, routing the traffic through the Pi 5. This setup will let me accurately assess the Pi 5's routing performance by eliminating the internet connection as a variable.
Here’s the setup:
