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

[eRCaGuy]

I've noticed that this problem of gvfsd-smb taking up 50% of my CPU
(100% of 1 of 2 cores) only exists if I am not logged in to a Windows
share first via the terminal. In other words, I have Windows shares I
like to access with my Linux computer running Xubuntu 16.04. If I open
nemo (my main file manager I like) and click on "Network" on the left-
hand side, then click on my Windows computer name ("Gabriel-Toshiba" in
my case), gvfsd-smb locks up my CPU.


*However,* if I *first* mount one of my windows shares via the terminal with this command: 

"sudo mount -t cifs //192.168.0.106/dev /home/gabriel/mnt/test -o
username=gabriel,uid=gabriel,gid=gabriel"

and *then* navigate through my network via nemo, it works fine (I am
able to actually navigate into my network shares, including others I did
*not* mount), and it does NOT take up 100% of one of my CPUs!


So, that's my work-around for now: use the terminal to mount a share before trying to click around the Network in a file manager.

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.
