Title: Weird rendertimes when using Backburner
Post by: fflasshh on 2021-10-14, 09:57:50
Hi,
I'm using backburner to render animations, I have 2 rendernodes, and 1 workstation. Rendernode1: amd 3950x, rendernode2: amd 2970wx, workstation: amd 5950x.
On my last project, the rendertimes, most importantly the parsing scene times look like this:
3950x: parsing scene 00:40 sec, total rendertime: 4:50
5950wx: parsing scene: 1:30 min, total rendertime: 5:10
2970wx: parsing scene: 3:24 min, total rendertime: 7:01
So, that's weird. Parsing scene is a single core task. How is the 3950x faster, than the 5950x? It should be the opposite.
I know, the threadripper is slow in sinlge core tasks. But the 2970wx needs 6 times longer to calculate parsing scene, then the 3950x. 6 times longer, How can this be?
All the assests are on the workstation (5950x), the rendernodes get the files via network share.
I ran also cinebench tests singe and multicore. Those times are OK, as they should be - 5950x is the fastest, even in single core. So there is someting with Corona render or max/backburner which causes weird rendertimes. Any advice? thanks.
