  Where are you downloading from?
  Have you run other tests, pulling down from other servers/address?
  
  I haven't noticed any slowdown in any of the nodes in Sydney myself.
  
  Thanks-
  Andrew.

  Generally, anywhere
  
  I have only been get 20mb/s down on beta.speedtest from a several servers but 500Mb/s+ up and 1ms ping,
  
  That is on a $20 server instance running server 2012 r2, my ubuntu web server is having issues even downloading sentora

  This is the kind of thing that's really better handled via a ticket then on the forums. If you do open a ticket, please include a traceroute/MTR to/from your server.

  I did talk to support but is seems to be a PFSense related issue.
  
  I had no issue with IPFire as I firewall appliance. It seems to be a combination of PFSense/BSD and the VirtIO drivers/KVM.
  
  Has anyone else come accross this before?

  IIRC, disable TSO on the virtual NIC and your throughput should improve. The FreeBSD virtio driver has problems with this.

  Hi,
  Have you disabled
  - Hardware checksum offloading
  - TCP Hardware Segmentation offload
  Im currently running a few Pfsense nodes, and those options have generally solved my issues.
  If you are putting nodes behind the instance, make sure you are setting the correct MTU, It makes a big difference

  Thanks AHBIT and devicenull,
  
  The default install of 2.2.6 had TSO and LRO off by default,
  
  The issue was resolved by also disable hardware checksum offloading, I now get ~600 down and ~600 up.
  
  Thanks Again, TheFatHacker
