2 days before, I removed a Intel e1000 pcie card from my ESXi-Server to free one PCIe-slot which is needed for a RAID-controller.
Instead of the e1000, I configured the onboard-NIC with RTL8111D, which is working from the first moment.
While googling around, i found some postings about handling poor network performance within guest OS such as W2008.
Using iperf on 2 Windows 7 VMs, I recognized really poor network throughput - with 12-15Mbits/s far away from other experiences with 10-13Gb/s!
The network connection is shown to be 10Gb in Windows 7, but I learned that this is an artificial value.
On both Win7 VMs VMXNET3 is used - but no improvement.
I also tried to activate JumboFraes 9000 - no help.
I also disabled "TSOv4" on both VMs NIC-Properties - no improvemnet.
What can I do ? At the moment I cannot re-install the e1000-NIC, as I need the PCIe-slot.
