I have a direct link between your gaming setup and the server. The rig runs Windows 10 Server on Ubuntu LTS, with a 10G card and 10GB of storage on the server. The connection works well at first, around 700MB/s, but after halfway through the transfer it drops to 4.50MB/s. I've adjusted many parameters, but I'm unsure what's causing the issue—possibly an offload or power setting problem, though all are unchecked.

The system is operating at maximum capacity, approaching its performance limits.

Speed adjustments aren't happening to 4.5MB/s. My connection to the server works well on other devices too. Stability remains at around 114MB/s over a gigabit Mac. The issue seems linked to the network adapter settings, which I've tweaked many times.

In contrast, with just standard HDDs, the initial transfer speed reaches up to 90MB/s but then stops completely when the server buffer fills, causing the average speed to drop to single digits. Since you're moving more than 10GiB, it will likely start faster but take longer to recover, making single-digit readings quite normal. To check if this is the issue, log in to the server and run iotop—it should show whether your storage is already at capacity during that process.

Transferring two files simultaneously between two machines causes issues. The problem stems from conflicting network interfaces—one uses a static IP while the other relies on DHCP. The NICs are interfering due to differing subnets and IP ranges.
