I tried to replicate the test that Scott made and I found something very interesting. MY SYSTEM/SETUP (same as Scott's): $ pacman -Q dolphin libssh openssh dolphin 25.08.3-1 libssh 0.11.3-1 openssh 10.2p1-2 Gigabit wired network. TESTING: 1. Generate 4GB file filled with random data: dd if=/dev/urandom of=LARGE_TEST_FILE bs=1M count=4096 status=progress 2. Transfer using scp from the terminal: $ scp LARGE_TEST_FILE local-server:archlinux/ LARGE_TEST_FILE 100% 4096MB 82.3MB/s 00:49 3. Transfer using **fish** protocol in Dolphin: It worked around 11X slower than scp did. See the attached download stats screenshot (FISH transfer speed in Dolphin - https://bugs.kde.org/attachment.cgi?id=186813) 4. Transfer using **sftp** protocol in Dolphin: Unexpectedly, it gave me approximately the same results. See the attached download stats screenshot (SFP transfer speed in Dolphin - https://bugs.kde.org/attachment.cgi?id=186815) So, my conclusion is SSH transfer is "broken" over fish protocol. I don't know the technical differences between fish and sftp protocols, but certainly the former needs an in depth overhaul. The positive note, though, it was learning that we at least have sftp to do fast transfers in dolphin. Regards. -- You are receiving this mail because: You are watching all bug changes.
