OK, so a few things to check/try;

 

  • Ensure you are using VMXNET3 vNICs
  • Enable TCP Segmentation Offload (TSO) by modifying 'sys db tm.tcpsegmentationoffload' and setting it to enable
  • Enabling TSO support also enables support for Large Receive Offload (LRO) and Jumbo Frames
  • If this still doesn't help try disabling Large Receive Offload (LRO) in the hypervisor
  • I also believe enabling SR-IOV in the hypervisor can help
