Fedora 28 Server
Fedora 28 Workstation
dd-wrt 802.11n Broadcom based router
Connected wirelessly 5GHz, wired ethernet cable is physically
disconnected from Server
File transfer from Workstation to Server
scp: scp itself reports ~620KB/s; where nload on the server reports ~4.9Mbit/s
smb: GNOME reports 4.9MB/s; where nload on the server reports ~39.8Mbit/s
Why? That's rather unexpected.
Command is
scp test.bin f28s.local:/srv/scratch
Using nc, I get speeds slightly faster than smb. OK so encryption? If
I connect wired, and then 'nmcli c down <ID>' to disconnect the
wireless connection:
scp: 12MB/s, nload ~101Mbit/s
smb: nload ~96Mbit/s
Sooooo, it's not encryption. Why would scp be this much slower only
with a wireless connection? And using:
rync -avzhe ssh test.bin f28s.local:/srv/scratch
Over wireless, this is just as bad as scp.
