gvfs SLOOOOOWWW (nautlius and smb)

Stratus_ss · Sep 6, 2013

Has anyone else noticed that GVFS and a file browser (thunar, nautilus, PCMan... whatever from lxde) all use gvfs and are all ULTRA slow?

I noticed this today when my dad came over to pull stuff off my server. Normally I just use rsync/ssh, but I have the samba shares available for easy browsing.

Anyways, Windows <--> Linux gets 45MB/s (ish), Linux <--> Linux via cifs mount is 60MB/s (ish), Linux <---> Linux via a file browser and gvfs is 2-5 MB/s???? WTF?

I have spent the last several hours chasing my tail on this. I have tried the following distros:

CentOS
Arch (up to date)
Ubuntu 12.04
Mint 13
Mint 15

All have the exact same problem, using a file browser and consequently GVFS gives **** poor performance

Anyone have any help here?

If I go to a computer (any linux computer) and use the file browser... I top out at sharing around 3-4MB/s. If I do

Code:

mount -t cifs //stratus-laptop-wire/Steam /mnt

and then do the file copy I get 20-22MB/s (laptop hard drive being the limiting factor here).

I dont get it

Just tested my setup:

NFS: 98MB/Sec
smbclient: 79MB/Sec
gnome file browser: 27MB/Sec

So I do see a similar case, though not by the same margin. All cases were video files that were not cached on the server side. Receiver had a SSD, over gigabit. Server was Ubuntu server 12.04.3 LTS and client was Ubuntu 13.04. Dualstack IPv6, forced to connect IPv4 for the tests. Samba has a relatively simple config (no domain, but does have a printer share via cups, and audit logging enabled).

Relevant samba performance config:

Code:

	socket options = SO_KEEPALIVE TCP_NODELAY IPTOS_LOWDELAY IPTOS_THROUGHPUT 
	use sendfile = Yes
	write cache size = 262144
	large readwrite = no
	read raw = yes
	write raw = yes

Thanks for the test. At least it confirms my issue.

Your number are better, however partly probably due to the SSD

In my case I was going from a RaidZ of 1.5TB drives to a mechanical 7200 RPM drive
