Description Fabby 2020-02-09 20:44:52 UTC 
SUMMARY
When copying files to NAS using CIFS over WiFi, Dolphin copies take >2 times longer than the same file copied using cp

STEPS TO REPRODUCE
1. create 1GB file: head -c 1G < /dev/urandom > /tmp/1G
2. mount NAS cifs: mount -t cifs -o rw,username=UID,password=PWD,domain=WGP,vers=1.0 //SERVER/SHARE/DIRECTORY /media/DIRECTORY
3. drag and drop /tmp/1G to /media/DIRECTORY. Measure time.
4. execute: cp /tmp/1G /media/DIRECTORY. Measure time

OBSERVED RESULT
Dolphin gets 7MiB/s, cp gets 18MiB/s

EXPECTED RESULT
Dolphin = cp
