I'm trying to transfer UDP packets from Host to VM using iperf command at 850 Mbps bandwidth. In the attached screen shots. I am dropping about 2-3% of my packets. I have MTU=9000 in all the ifcfg files for all the VNICs and NICs.
What configurations do I need to change to stop packet loss between Host and VM?
I've tried increasing the rx ring buffer.
Also, using the vmware-netcfg tool, I set up 2 bridge connections for the virtual NICs to latch on too. Sorry if I'm not using the correct vernacular.
