Good Morning,
I am looking into some general network performance issues on my network and I would like some clarity on what I should expect to happen before I raise a ticket for any potential faults/misconfigurations.
I am testing the transfer speed between 2 VM's using a product called Lan Speed Test. This is a fairly simple client server application that sends an amount of data each way between the two applications and measures the speed throughput. I am getting the following results and would like to know if that is what you would expect to get :-
VM1 -> VM1 (bypasses network) - 17Gbps upload, 14Gbps download - I think would be about right
VM1 -> VM2 (same physical esxi 7 host - 1.7Gbps upload, 0.5Gbps download - I would expect something more like 10Gbps each way?
VM1 -> VM2 (different Physical Hosts same subnet, 2x10Gb physical network connections) - 2Gbps upload, 0.85Gbps download - again I would expect more like 10Gbps each way
The VMware Hosts are both running Esxi 7, standard vSwitch, 2 physical 10Gb network adapters connected to 2 Meraki MS425 10gb switches. Each VM is using the VMXNet3 adapter and report 10Gbps connection speed.
I understand that from this limited information you cannot make a diagnosis, what I am trying to find out is more - is this the expected behaviour or would you expect (as I do) to see better network transfer for the second and third tests?
