network rendering - not as fast as I'd hoped...

[cahaldallett]

Hi All,

We have just started rolling out octane to our workstations - double GTX 1080s in each machine. I'd expected that when I added a new render node, the render time would decrease by 50%, like it always has in the past when doing CPU rendering.

Perhaps it is the scene not having enough time to stretch its legs? One machine the frames were rendering at 20s a frame, but with two machines (that's 4 x 1080GTXs) it was 14s. I'd expected it to be 10s?

Can anyone advise if this is normal? Also is it possible to have each of the new nodes render out separate frames, rather than contribute to the one frame each time?

Thanks!

A possibility for the slow-down could be that the networked 1080s set to priority render

Could also be that you only render in a very short time. The slave take some time to load from network before it starts the render, so try a scene that take about 10 min or longer and not just a few seconds.

yeah network render is not optimal for quick frame renders, animation actually took much longer on network when it's like 5-10 second per frame than on single machine.. takes time to grab the render from the network and asseble

- having everything local is optimal, so there is a point to buying those expensive expanders
