I have experienced this bug on two Ubuntu desktop 12.04.5 x64 systems, copying to a debian 7 / samba 3.6 share. I haven't tried other OS versions though.
Steps to reproduce: Open remote share so it gets gvfs-mounted under ~/.gvfs cd ~ cd .gvfs/path/to/remote/samba/share cp ~/huge_file . Speed: roughly 5.5 Mbyte/s sudo mount /remote/samba/share /mnt cp ~/huge_file /mnt/ Speed: roughly maxes out wire. -- 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
