Capturing at Gigabit speeds however only Unicasting at 50Mbps

[Clebboii]

Hi all,

I am new to FOG and am currently trying to get it setup within my workplace. If there are any troubleshooting requirements or logs you need to see, please let me know / spell it out fairly plainly.

I have currently setup my FOG server on a 1GBe network, with plans to upgrade to fibre 10GBe. My server is running on a Fedora 41 machine and I am mainly imaging Windows 11. When I am capturing images I can see that the speeds are reaching 1GBe speeds however whenever I try to deploy, using unicast, each unicast is stuck at 50Mbps.
When I say 50Mbps, I can unicast 1 machine at 50Mbps (takes around 2 hours), or I can Unicast 3 images / machines at 50Mbps (150Mbps over the switch) which still takes about 2 hours. My IT brethren in the workplace have asked me not to use multicast.
I am mostly imaging Dell Laptops with secure boot and Bitlocker turned off, so this shouldnt be the limitation.

I have used iperf3 to test the connection between the windows machines and the linux server, and everything is running at close to 950Mbps. I have also run multiple speedtests on both the server and clients and all are as expected (about 500 up and down). The client machines are using i9’s and i7’s, so I don’t think it is decompression slowing things down. I have also tried to image no compression on the image and again I am limited at 50Mbps, as it was not compressed it took close to 4 hours.

This feels like a unicast limit, as if either A) FOG limits each unicast connection or B) hardware in between (such as the NIC or Ubiquiti switch) are limiting ftp / udp on the network.

Any thoughts?

Capture Task

Server Setup

And some evidence that the server and connection can transmit at Gigabit
