Issue detected with 10G speed on primary subnet.
Hi, your setup shows some interesting behavior. With a 10G baseband and a Mellanox SFP+ connected through a CRS305-1G-4S+IN switch, you're experiencing bandwidth caps depending on subnet configuration. When both devices share the same subnet, you hit around 6.5GB/s, while giving them separate subnets pushes performance up to about 9GB/s. Having two NICs on the same device isn't an issue here. The real challenge comes when you add more devices needing full bandwidth—like additional PCs or NAS access. You might want to consider assigning dedicated subnets or using a more robust switch with better QoS support. If you need further optimization tips, let me know!
