Hello, I was testing NetBSD VM on ESXi with vmware vmxnet3 interface on 10GbE network and noticed a max throughput of around 3Gbps when measuring with iperf. I did set "10GbaseT mediaopt full-duplex" manually just to make sure, but didn't notice much improvement.
Linux VMs manage almost 10Gbps, so no issues there. Anyone knows why NetBSD vmx driver performs so poorly? Cheers.
