Thank you for looking into this problem. What I observed additionally: * the very first upload copy with nautilus is normal maximum speed (~110 MB/s) * then every upload copy is about 7 MB/s * if I change the file ending to ".exe" and upload, I get maximum speed!
Results to your requested data: 1st cp: time cp -T /home/florian/upload.iso /mnt/cifs_nas_media_flo/upload.iso real 1m21,701s user 0m0,054s sys 0m4,832s 2nd cp: time cp -T /home/florian/upload.iso /mnt/cifs_nas_media_flo/upload.iso real 1m23,342s user 0m0,059s sys 0m4,879s => so maximum speed (8GB need ca. 80 seconds) 1st gio copy: gio copy -pT /home/florian/upload.iso /mnt/cifs_nas_media_flo/upload.iso Transferred 114,8 MB out of 8,0 GB (6,8 MB/s)^C 2nd gio copy with ".exe" file ending: gio copy -pT /home/florian/upload.exe /mnt/cifs_nas_media_flo/upload.exe Transferred 8,0 GB out of 8,0 GB (115,0 MB/s) So all this speed drop is somehow linked to the file ending. What could interfere just because of different file endings? And why are only nautilus and gio copy affected and not all copy utilities? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1782535 Title: cifs - poor upload speed with nautilus compared to rsync To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nautilus/+bug/1782535/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
