I am using a Fedora KDE 43 laptop with the KDE Connect app to connect my KDE desktop and Android device. I’ve noticed a significant difference in file transfer speeds depending on the method and direction I use to transfer files between my Android device and laptop.
-
When I use KDE Connect from my laptop to mount and browse files, then copy them to my download folder, I get speeds of around 10 Mbps on my local network. I assume this is because mounting and copying files uses SFTP or FTP protocol.
-
When I open the Android app and use the “Send files” option to select and send a file, I achieve speeds of around 50 Mbps. I believe this method uses an HTTP server for file transfer.
For context i am using transferring one big 30gb file, not small files or folders in both cases.
Am I correct about these protocols?
