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 Ubuntu Desktop Bugs, which is subscribed to gvfs in Ubuntu. https://bugs.launchpad.net/bugs/1236619 Title: gvfs smb / cifs file copy performance is terribly slow To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gvfs/+bug/1236619/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
