[Bug 1409032] Re: gvfsd-smb: very high CPU utilisation

[Brett Bogert]

After not be satisfied with any of the above workarounds to the problem
I decided to take a look at the problem and see if I could come up with
a "cleaner" workaround or fix.

I found that this problem occurs in Ubuntu 16.04 with Unity Gnome 3.18
GnomeShell Gnome 3.20, Budgie Gnome 3.18 and Fedora 24 Beta.

After some troubleshooting I found the following solution that does
not require changing executable permissions or removing packages:

1- Make a backup copy of the smb.conf file in /etc/samba.

2- Edit the /etc/samba/smb.conf file using your favorite editor
and add the following line under the "[global]" statement:

name resolve order = wins lmhosts bcast

The file should look like this:

[global]
name resolve order = wins lmhosts bcast

3- Save the file and reboot.

The problem should be fixed and you should notice that the
"Network" Icon and label shows up much quicker in your
file browser than before and the 100% CPU usage is gone.

Hope this helps.

  gvfsd-smb: very high CPU utilisation

Bug description:
  Example:

  I use Virtualbox and mount a .vdi on an SMB server. Using gvfsd-smb
  (browsing within Gnome to find the share), gvfsd-smb uses up to 50%
  CPU which slows down the entire system when accessing the network
  share. Mounting using sudo ($ sudo mount -t smbfs -o
  guest,nounix,noperm //server/share /media/share) so that cifs is used
  uses around 8% CPU. The difference is dramatic!

  If I didn't have sudo access my machine would grind to a halt when
  trying to use the remote share.
