network rendering through VPN

[jimho]

When seting up a new studio nearby,I am doing an interesting test on the VPN network rendering,
guess there might be others also interested in it, so I post it here,

The result first: it works! though seems not fully efficient,

I hope to see if there is any way can make the performance better.
The testing background:

• Studio 1:
  • workstations: 1 standalone(as master)+2node as slaves,
    internet connection: 300Mbit fiber Adsl(upstream speed: 30Mbit)
  Studio 2:
  • workstations: 1 node as slave
    internet connection: 500Mbit fiber Adsl（upstream speed: 50Mbit）
  VPN (L2TP) is setup between Studio 1 and Studio 2,
  Remote desktop works and connection between all octane slaves to the master is made and working( 2 through Lan and 1 through VPN)
  Testing scene: 2GB in size

Looking Great, right? Now the issues coming,

• 1, since the Vpn is relatively slow than the LAN the time for transfering the scene to the remote slave is a bit long, so it start running much later than the native slaves, anyway, this is known and as expected,
  2, when the remote slave is start running, there is long stop between the fully working period regularly,while the master and native slave are all fully engaged working.

My question is though the scene is fully transfered to the slave's Vram, there should not be too heavy data transfer between the master and slaves which make the huge gap in performance,

Anything I can do to make it better?(No upgrade for internet connection speed available at the moment...)

Hi,
yes, VPN is the perfect solution for Net rendering over internet, but, you should need at least 1Gbps connection for a smooth experience.
Please consider that the Render-Node has to send back to the Workstation the rendered frame buffer tile.
The more complex is the frame buffer, the more data the Render-Node has to send back.

Thanks Beppe,
Is there any settings that can make the Frame buffer tile smaller or simpler?
