Downloading issues

I have the ex2 ultra and I mapped the drive to my computer. I’m using a gigabit switch to connect the 2, and I have a 300/300 mbps internet connection. Am on os3 and have a WD 3Tb smr drive as jbod.

When I use transmission on the ex2 ultra, I get my full 300mbps. When I download via vpn through docker, I can only use a max of 100mbps.

I though I figured out a workaround, and used my torrent client on my pc and just download the file on to the mapped drive. Turns out it only goes to 100mbps that way as well.

Has anyone experienced this issue before?
