Bug#748362: gvfs-fuse: Low transfer speed when mounting smb share using gvfs-mount vs. mount.cifs

[Peter Graversen]

Package: gvfs-fuse
Version: 1.20.1-1+b1
Severity: normal

Dear Maintainer,

Transfering files from an Synology smb share is slow where the share is mounted
with gvfs-mount or Nautilus. The speed is ~50MB/sec, where is should be
~100MB/sec. If the share is mounted using mount.cifs the speed is as expected.

Reproduced using a 1.1GB file:

gvfs-mount smb://synology-nas.local/media
time cp /run/user/1000/gvfs/smb-share\:server\=synology-
nas\,share\=media/Movies/TS_01_1.VOB /home/user/Downloads

real    0m20.883s
user    0m0.016s
sys     0m1.492s

sudo mount.cifs //synology-nas.local/media /home/user/Downloads/temp -o
user=user
time cp /home/user/Downloads/temp/Movies/VTS_01_1.VOB /home/user/Downloads

real    0m10.486s
user    0m0.020s
sys     0m1.000s
