From the iperf client output we can see that we reach a total throughput of 2. Above in Windows R2 with an emulated E adapter the native guest operating system device driver is in use. You might just need to refresh it. The e maintainers would like to end this duplication and put the e driver into a stable maintenance mode. The ee driver, instead, supports PCI-Express adapters.

For most operating systems, changing the network adapter is trivial down the road. The e driver maintainers have resisted doing so, but Linus, having also been burned, agrees. For more information on network types, see Understanding networking types in hosted products Also, in at least this test setup the newer EE performed actually lower than the older E Two Windows R2 virtual machines, one as iperf server and the other as fs, with the test running in 30 seconds.
Since the newer driver also supports those chipsets, there are two drivers with two completely different bodies of code supporting the same hardware. Fast forward to current day times.

The VMware administrator has several different virtual network adapters available to attach to the virtual machines. E — which will emulate a 1 Gbit Intel EM card, and is available for most operating systems since the generation of Windows Server The virtual adapters belong to either of two v.
It is a newer driver which is seen as being better written and easier to maintain. The virtual machine will see a 10 Gbit virtual NIC attached to a virtual switch inside the host, but the VM will never see the physical interfaces which could be of any speed.
From the iperf e000 output we can see that we reach a total throughput of 2. This article explains the difference between the virtual network adapters and part 2 will demonstrate how much network performance could be gained vz selecting the paravirtualized adapter.
You might just need to refresh it. Bs we need to understand the background of the state of virtual machines. Consider those hardware offloading improvements combined with the addition of 10Gbps networking, it made the EE a great improvement in network adapters.
The E offered gigabit networking speeds, then the EE introduced 10Gigabit but also important hardware offloading functionality for network traffic. I simply dont understand. Posted by Tanner Williamson 0 comments.

VMware and Intel both worked to ensure the drivers for the Intel E and EE adapters were preloaded on all modern operating systems. For Linux guests, ee is not available from the UI e, flexible vmxnet, enhanced vmxnet, and vmxnet3 are available for Linux.
