So, I tried to add some prints.
I have mapped ratio about 78 while scp-ing the file. Distress suddenly raises
from 0 to 100. At this poing, all the processes are swapped out.
I guess it happens if scp is faster than the local disk which happens if
I scp-ing over GE from desktop (with fast disk - and reading) to laptop (slow
disk - and writing).
This is my settings.
