***

STEPS TO REPRODUCE
1. view source folder (on the computer) and destination (on remote device) folder side by side (split view)
2. copy a large file (or files)
3. copy is quite slow - now close dolphin, and observe an order of magnitude better copy speed.

OBSERVED RESULT
When not watching the destination and source folders while copying with dolphin, the copy speed is much greater.

EXPECTED RESULT
It should not matter if we view the folder while copying...

ADDITIONAL INFORMATION
ssh seems to be receiving a lot of data while copying with dolphin viewing the folder (about the same receive data rate as send), once dolphin is closed, ssh doesn't receive any data, and send data rate increases dramatically.
