Do you experience problems during downloading?
Check your connection in Status and Interface settings window.
Use Test Server in Config > Servers.
We will probably ask you to do a test using only basic settings.
Do you experience problems during repair or unpacking?
Enable +Debug logging in the Status and Interface settings window and share the relevant parts of the log here using [ code ] sections.
The slider is at 59% (I just randomly selected that to test) which is shown as it should cap it at 6.49 MB/s (which is correct). But my download is still coming in at 10.4 MB/s.
And 10 MB/s is below the max of 6490 MB/s you set, so SAB is working correctly.
So you've filled that your max linespeed is 11000 MB/s. That is 11 GB/s, and around 90 Gbps. That would be nice, but I don't think you have such a connection
EDIT:
As SAB achieves 10 MB/s, I think you have a 10 MB/s line. Not 11000 MB/s
