I can confirm this too, both with nautilus and cp. At work we recently switched to the latest LTS (14.04) but the same behavior was consistently observed on multiple Ubuntu computers running both 14.04 and 12.04 when communicating with our NAS.
Windows 7/8 -> NAS : 50-60MB/s Ubuntu -> NAS (GVFS) : 5-10MB/s Ubuntu -> NAS (mount.cifs) : 50-60MB/s No need to mention, we obviously use /etc/fstab on most machines now, but I'd love to be able to have those speeds without having to fiddle with the configuration every time we get a new computer. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gvfs in Ubuntu. https://bugs.launchpad.net/bugs/1236619 Title: gvfs smb / cifs file copy performance is terribly slow Status in “gvfs” package in Ubuntu: Confirmed Bug description: Copying moderate-size files to a samba share using gvfs is ridiculously slow compared to doing the same via mount.cifs. For example: $ ls -sh testfile 1.2G testfile $ time cp testfile ~/mnt/share-gvfs/ real 2m37.053s user 0m0.056s sys 0m5.120s $ time cp testfile ~/mnt/share/ real 0m26.134s user 0m0.004s sys 0m1.724s I'm running Xubuntu 13.04 (raring) amd64, gvfs 1.16.1-0ubuntu1.1.
