Hi,
For the purpose of speeding up light building we got 2 used servers with 2 Xeon E5-2695 V2 (12 core 24 threads) processors each.
Beside them we have also 2 desktops with i9-11900F (8 cores 16 threads).
Every machine has 128gb of ram memory.
I have Swarm Agent running on all of them and one i9 with the Swarm Coordinator. They all can ping each other.
I’m using this command line to build lightning:
“PathToTheEngine\Engine\Binaries\Win64\UE4Editor-Cmd.exe” “C:\GameDir\MyGame\MyGame.uproject” -Run=ResavePackages -BuildLighting -Quality=Preview -MapsOnly -ProjectOnly -AllowCommandletRendering -Map=MyLevel -Messaging -stdout
The issue I have is performance when using servers to build lighting.
I did test different combination but one i9 is starting the build always.
When building only on one i9 it takes 2003.87 seconds to finish.
When using swarm:
- with two i9 it takes 1193.30
- with one i9 and one server it takes 2100.02
- with one i9 and two servers it takes 1904.70
- with two i9 and two servers it takes 1330.16
I understand that these servers are pretty old but what I do not understand is why they are slowing the build.
This is how Swarm Status looks like on main machine:
Does anyone have experience in similar setups?
Thanks in advance!
