Is there any special guide, how to setup cisco 10 Gigabit switched for nutanix environments?
Im using vsphere 5.0 U3 with nutanix.
Should jumbo frames be enabled?
Is it possible with iperf inside the cvm to get 9 Gbit/s with with one process?
I get 1,57 Gbit/s
Good hints from Intel. The INtel nics are onboard. Which PCI Express speed X4,x8,x16?
This graph is intended to show (not guarantee) the performance benefit of using multiple TCP streams.

Maybe useful script:
For me, I had 10 machines to test, so I scripted it instead of running any commands by hand. This is the script I used: https://github.com/dak1n1/cluster-netbench/blob/m
A single one‐vCPU virtual machine can drive 8Gbps of traffic on the send path and 4Gbps traffic on the receive path when using standard MTU (1500 byte) frames.
Using jumbo frames, a single virtual machine can saturate a 10Gbps link on the transmit path and can receive network traffic at rates up to 5.7Gbps.
