VMware Slow Network Performance

If you experience much slower network performance in VMware guests than that in the host, try the following tweaks which may help improve the throughput.

  • Edit the VMX file to use: ethernet0.virtualDev = “vmxnet3”
  • Edit the VM Settings for “Network Adapter” to use “Bridged” Network connection AND also checked the box to “Replicate physical network connection state”
  • On the guest, go into Device Manager > Network Adapter and changed the following “Advanced” settings for the vmxnet3 Ethernet Adapter:
    • Property Value
      • Jumbo Packet Jumbo 9000
      • Large Send Offload V2 (IPV4) Disabled
      • Large Send Offload V2 (IPV6) Disabled
      • Speed & Duplex 10Gbps Full Duplex
