Hi, we’re running the latest FOG 1.5.10, trying to deploy to a Optiplex 3080.
FOG boots PXE, and I can deploy a image.

Yes these PCs come with NVME drives.

Issue is the deployment speed, it changes from below 1gb to over 8gb, same deployment to same machines, no other changes.

Done every firmware update / fog update, still various deployment speeds.

Got similar Dell UEFI only 3000 units on a flat test network & they all behave the same.

Has anyone come to a solution for this problem.

We’re a school with over 60 of these Dell 3000 & 3080 units - with more to come.
Older Dell 3010, 7010, 790 units all run at higher speed, over 8Gb/min in legacy.
New Dell in UEFI slow, again between 2-3Gb/min.

We’ve tried updating the Kernel & running latest Fog 1.5.10, same issue.

Is the problem the new chipset, NIC, or NVME drives??

Any help of pointers will be appreciated.

Thanks.
