The vmxnet3 one s a virtual 10G NC. The seed doesn't matter because the pCi bus sets the limit.

Hello JB,

Thanks for the reply. 

I used Iperf3 tool and realized  that am getting 13Gps on Vm level and i was getting 18Gps on physical host to physical host. 

my switches show no alerts or any dropped packets or bottle necks, the cpu is normal, 

Kind Regards
