Copying from local machine to a remote host with sshfs (dolphin, fish://) is very slow. For example copying an 50MB test file from my computer to my VPS: With scp: ~5 MB/sec With dolphin (KIO, fish://): ~500 KB/sec Another server: With scp: ~2 MB/sec With dolphin (KIO, fish://): ~80-90 KB/sec Reproducible: Always
another performance example: host: openSUSE 13.2 client: virtualbox with OpenSUSE tumbleweed and Plama 5.3 with scp: ~ 90-100MB/s which nearly reaches the 1GB/s link speed. with dolpin's sftp:// only 10MB/s
I'm experiencing the same problem in Dolphin 18.04.0 in openSuSE 42. fish:// protocol in Dolphin gives about 30 KB/s, while simple scp in terminal gives 500 KB/s.
It is even slower when copying from one ssh remote to another. I've got these results testing copying KIO fish: 1. server A -> local: 1100 KB/s 2. local -> server B: 180 KB/s 3. server A -> server B: 24 KB/s
