Javid,
I am running a script which copies a 1Gb files to and from the shared
driver. Am then dividing the time taken by the size of the file. I know it
is very hacked up :), but it should at least give some approximations.
Thanks.

Hello Guys,
I am having some problems with configuring SAMBA with regards to
performance. We are running SAMBA 2.2.3a on Dual PIII 1Ghz machines with
512MB of RAM. The server is running on a default server installation of Red
Hat 7.2. We have a 500Gb RAID 5 drive using the Promise SX6000 Raid
controller.
Currently we are only getting a throughput of ~5MB/S for writes and
~13MB/S for reads. Comparing that to NFS which yealds ~15MB/S for reads and
~13MB/S for writes. This clearly rules out the Hardware bottleneck since XFS
is able to perform better on the same hardware. Here is the smb.conf I am
using currently
===SMB.CONF===
[global]
workgroup = MYGROUP
netbios name = {HOSTNAME}
wins server = {WINSSERVER}
server string = {HOSTNAME}
security = SHARE
encrypt passwords = Yes
log file = /var/log/samba/log.%m
max log size = 50
socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192
dns proxy = No
oplocks = No
level2 oplocks = No
[homes]
comment = Home Directories
read only = No
browseable = No
[Data]
comment = Data Backup Directory
path = /home/gm/data
guest account =
valid users = spirian
read only = No
======
I was wondering if there is any documentation for fine tuning SAMBA. Any
help is appreciated. Thanks.
