Description Andrus Lepik 2022-05-08 04:24:10 UTC 
SUMMARY
I've experienced extremely slow SFTP file copy to remote in Dolphin (~250kb/s) ever since I can remember. It's not a connection issue, tested by logging in through SFTP and putting the file, the speeds were as good as expected (~7.5mb/s). I also tested using scp in shell, the speeds were good. 
For testing I used one large file of about 800mb to eradicate small file copy issues.

STEPS TO REPRODUCE
Copy any file to remote server using Dolphin and SFTP.

OBSERVED RESULT
Dolphin SFTP copy is over 20 times slower than SFTP through shell.

EXPECTED RESULT
Roughly comparable speeds in Dolphin SFTP and shell SFTP.
