Networking performance between 2 VMs

$
0
0

I have 2x VM's, both located on the same ESXi6 server.

The vswitch is setup correctly and both VM's are on that same switch.

The network is a 1GB interfrace, and both VM's have 1GB interfaces.

However, I can only achieve 1MB/s between the 2 VMs.

Looking for ways to diagnose and fix this issue.

Suggestions, questions, clarifications, please let me know.
