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

[cogset]

I think I may have the same issue in Trusty, possibly even worse: the
gvfsd-smb process would randomly start and totally max out the CPU for
no apparent reason - the thing is, not only I don't use samba at all, I
have actually *purged* all samba packages from this system.

I really can't see how this process, which should be spawned by samba,
should even start at all (let alone load the CPU to its max) when samba
isn't even installed any more in my system.

This being an old laptop which easily overheats, after getting nowhere
trying to figure out why gvfsd-smb does this, I've resolved to remove
the executable bit from  gvfsd-smb and  gvfsd-dnssd (which also starts
for no apparent reason) and finally got rid of this big issue.

But nonetheless I believe that such an annoying (and potentially
harmful) long-standing bug should be properly investigated and fixed
once and for all.

  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.
