I have found this bug on several computers running Ubuntu 16.04 and Raspberry Pi 2s and a 3 running Ubuntu MATE 16.04. With a quad core CPU, gvsfd-smb-browse seems to consume 100% of one of the cores.
On a Dell XPS13 laptop, this causes the cooling fan to come on. On the Raspberry Pi 2 and 3, it uses up excessive CPU resources preventing some processor-intensive apps from running properly and contributing to the CPU temperature rise. The solution that I have used is to remove the execute permission from the file as follows - execute from the terminal: sudo chmod 744 /usr/lib/gvfs/gvfsd-smb-browse This seems to prevent the rogue file from running and appears to have no detrimental affect on the running of the operating systems. Perhaps we can have a permanent solution implemented in the next Xenial software upgrade. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gvfs in Ubuntu. https://bugs.launchpad.net/bugs/1409032 Title: gvfsd-smb: very high CPU utilisation Status in gvfs package in Ubuntu: Confirmed Status in samba package in Ubuntu: Confirmed Status in samba package in Fedora: Unknown 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.
