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 Desktop Packages, which is subscribed to nautilus in Ubuntu. https://bugs.launchpad.net/bugs/1782535 Title: cifs - poor upload speed with nautilus compared to rsync Status in nautilus package in Ubuntu: Incomplete Bug description: I'm mounting folders from my NAS on my computer (Ubuntu 18.04) with cifs. Copying an 8 GB file... Upload (local -> mounted) - Nautilus/Nemo -> 6 MB/s - rsync -> 50-60 MB/s Download performance is also strange, but not my biggest concern. Download (mounted -> local) - Nautilus/Nemo -> 90 MB/s - rsync -> 50-60 MB/s rsync command (upload): rsync --progress /home/me/file.iso /mnt/cifs_media/ fstab entry: //nas/media /mnt/cifs_media cifs vers=3.0,uid=me,gid=me,credentials=/home/me/.smbcredentials,dir_mode=0700,file_mode=0700 0 0 Any idea, why Nautilus is uploading up to 10 times more slowly than rsync, although both using the same cifs, os, hardware, network etc.? PS: Further info for bug report 1) The release of Ubuntu: Ubuntu 18.04 LTS 2) The version of the package: Nautilus 3.26.3 3) What you expected to happen: At least same speed as with using rsync 4) What happened instead: See above To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nautilus/+bug/1782535/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
