 |
|
I got gigabit ethernet cards on both sides ( in my router and my pc ). But when i copy file via samba from router to pc i got speed about 8-9 MB/s. Here what i have got:
settings of ethernet card
| Code: |
(SSH:router) [~] $ sudo mii-tool
eth0: negotiated 1000baseT-FD flow-control, link ok
(SSH:router) [/mnt/smb/127.0.0.1/public/video] $ sudo ip link show dev eth0
2: eth0: <BROADCAST,MULTICAST,PROMISC,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UNKNOWN qlen 1000
link/ether 00:e0:4d:2c:38:74 brd ff:ff:ff:ff:ff:ff
|
samba server settings
| Code: |
[global]
dos charset = cp866
unix charset = utf8
display charset = utf8
workgroup = DGAP
netbios name = SHADOW
server string = Shadow ( user: %U )
security = SHARE
map to guest = Bad User
username map = /etc/samba/smbusers
log file = /var/log/samba.log
name resolve order = lmhosts hosts wins bcast
unix extensions = No
socket options = IPTOS_LOWDELAY TCP_NODELAY SO_KEEPALIVE
load printers = No
printcap name = /dev/null
disable spoolss = Yes
local master = No
hide unreadable = Yes
[public]
comment = public data
path = /mnt/data/samba/public
force user = nobody
guest only = Yes
[media]
comment = data [private]
path = /mnt/data/media
valid users = media
force user = media
force group = users
read only = No
create mask = 0664
directory mask = 0775
browseable = No
[services]
comment = services [private]
path = /mnt/data/services
valid users = media
force user = media
force group = users
read only = No
create mask = 0664
directory mask = 0775
browseable = No

Test of performance over la
| Code: |
(SSH:router) [/mnt/smb/127.0.0.1/public/video] $ dd if=Waking\ Life\ \[Пробуждение\ жизни\]\ \(2001\).avi > /dev/null
1187076+0 records in
1187076+0 records out
607782912 bytes (608 MB) copied, 8.84257 s, 68.7 MB/s

Plz help resolve this issue ? Maybe change mtu or smth? |

8-9 MB/s are quite OK for a default config.
You could try tuning Samba a bit, e.g. the network sockets.
Try addig following to [global] and see if it helps:
| Code: | | socket options = TCP_NODELAY IPTOS_LOWDELAY SO_RCVBUF=65536 SO_SNDBUF=65536 |

no difference at all  As i write before when using local address 127.0.0.1 i got 60MB/s ( it seems hard disk and samba limit ) , 1GB ethernet should provide speed up to 120MB/s but i have only 10 i would like to have at least 40-50 ... so where is bottle neck? =( |
