Im trying to locate the bottleneck on a 10g network between 2 esxi hosts.
Both machines have Mellanox 10g SFPs with a Cisco cable between. Both are running ESXi 6. I created a new vSwitch in each and added a VMNET3 NIC to each Win2012r2 VM, added the 10g Nics to the vSwitches, configured static IPs, set MTU to 9000 - all good.
Then in each VM I created a RAM disk and shared it. Locally, ATTO can read and write at about 2.5 GB/s but when I copy a file between the RAM disks on the 2 VMs it hits about 300 MB/s but thats it.
I'm new to 10g networking. Can anyone tell me where I'm going wrong?
