This packet is not received outside of the VM and after a timeout it is being fragmented and retransmitted.
VMWARE ESXI 6 SLOW NETWORK PERFORMANCE DRIVER
The problem is clear with packet 7 - the driver is trying to send a 16KB packet, above our 9K MTU jumbo frame.
VMWARE ESXI 6 SLOW NETWORK PERFORMANCE DRIVERS
Let's start with an example of network throughput performance from the Windows 8 Machine to Linux:Īs my next step I was planning on running some dtrace commands, and accidentally noticed that the drivers I have installed are the Solaris 10 version and not the Solaris 11 find /kernel/drv/ -ls |grep vmxnet3ħ8669 2 -rw-r-r- 1 root root 1071 Mar 27 01:42 /kernel/drv/nfħ8671 34 -rw-r-r- 1 root root 34104 Mar 27 01:42 /kernel/drv/amd64/vmxnet3sħ8670 25 -rw-r-r- 1 root root 24440 Mar 27 01:42 find. It's a great and easy to use tool and you can find precompiled version for almost any operating system. Throughout this post I'll use iperf to measure network performance. VM to VM network performance has been great between the Windows/Linux boxes once I enabled Jumbo Frames.

Solaris 11.1 as NAS, running the great napp-it software ( )Īll the machines have the latest VMware Tools installed and running paravirtualized drivers where possible. Windows 8 as my primary desktop, passing dedicated GPU and USB om the host to the VM using VMDirectPathģ. I have a variety of machines running in a virtualized form:ġ. I was also able to achieve some performance improvements but not to the degree I hoped to see. I am quite happy with the setup as it allowed me to eliminate 5-6 physical boxes in favor of one (very strong) machine. This post would follow my journey to achieve better network performance between the VMs. Recently I virtualized most of the servers I had at home into an ESXi 5.1 platform.
