Facing one weird issue on the Intel setup (We have 2 machines having Intel card -both side we have Intel xl710 having 40G speed).We are seeing just 1 Gbps of throughput with netperf,iperf etc using ESXi 6.5
Setup has ESXi 6.5 (latest VMware Tools install with adapter VMXNET3) on both DUT/Partner each having a VM on which we ran Netperf/iPerf.
We have updated latest driver and firmware on Intel.
Additionally@@ we have tried throughput in loopback mode with both Intel interfaces on same machine connected (below) just to make sure that its an Intel adapter issue on a particular machine but it doesn't seem to be the case
