--- Comment #3 from Scott <shagooser...@gmail.com> --- OK first off the slow speed is apparent in disk to disk transfers when both disks are connected to the same controller, the reported speed is 40 MiB/s. This is less than half the speed reached by Nautilus or Windows File Manager on the same hardware. My LAN is a Kubuntu 18.04 > Archer C7 Router > Ubuntu 17.10. The connection is via CAT 6 cable and each run is less than 15m. The tests I did involved a 3 GB movie file moved from a directory on the Kubuntu PC to the Home directory on the Ubuntu PC and then moved back to a folder in the a disk not containing the Kubuntu Home directory (ie a 2nd HDD). Both of these PCs have multiple HDDs so these tests were just transferring the same 3 GB file from one disk on the PC to another disk on the same PC. Please note these tests were back to back on the same hardware, run sequentially within 40 minutes, transferring the same file. In my ignorance I will state that it does not seem to be a SFTP problem on 2 grounds, 1/ Nautilus hits LAN transfers of around 100 MiB/s which is close to the expected top speed for a sustained domestic LAN transfer and 2/ I don't believe SFTP is used in a transfer from one HDD in a PC to another HDD in the same PC. I regularly deal in file transfers where the file sizes range between 20 GB to 70 GB and the speed difference is very noticeable, ie 5 to 10 minutes longer per file transfer. At the moment I consider Dolphin unfit for purpose and unusable. -- You are receiving this mail because: You are watching all bug changes.
