Hi all,
I set up a samba server into Debian 3.2.0-4-amd64. This runs as guest OS into
VirtualBox machine over OS X host OS.
Connection seems pretty good:
$ iperf -s
------------------------------------------------------------
Server listening on TCP port 5001
TCP window size: 85.3 KByte (default)
------------------------------------------------------------
[ 4] local 192.168.0.21 port 5001 connected with 192.168.0.20 port 52800
[ ID] Interval Transfer Bandwidth
[ 4] 0.0- 4.0 sec 256 MBytes 541 Mbits/sec
$ iperf -c 192.168.0.20 -n 256M
------------------------------------------------------------
Client connecting to 192.168.0.20, TCP port 5001
TCP window size: 23.5 KByte (default)
------------------------------------------------------------
[ 3] local 192.168.0.21 port 54463 connected with 192.168.0.20 port 5001
[ ID] Interval Transfer Bandwidth
[ 3] 0.0- 3.2 sec 256 MBytes 674 Mbits/sec
But reading transfer speed is ridiculous:
$ mount -t smbfs //user at 192.168.0.21/www Workspace/www
####################################
$ time dd if=/dev/zero of=Workspace/www/testfile bs=8k count=32768
32768+0 records in
32768+0 records out
268435456 bytes transferred in 0.144830 secs (1853452167 bytes/sec)
real 0m2.714s
user 0m0.008s
sys 0m0.350s
####################################
$ time dd if=Workspace/www/testfile of=/dev/null bs=8k
32768+0 records in
32768+0 records out
268435456 bytes transferred in 61.248506 secs (4382727 bytes/sec)
real 1m1.271s
user 0m0.007s
sys 0m0.287s
As you can see, reading speed transfer rate is approximately 4,18 MB/s when the
iperf test shows approximately 67,63 MB/s.
What?s wrong?
smb.conf file content is the following:
$ cat /etc/samba/smb.conf
[global]
server string = %h server
interfaces = eth0
bind interfaces only = Yes
map to guest = Bad User
obey pam restrictions = Yes
pam password change = Yes
passwd program = /usr/bin/passwd %u
passwd chat = *Enter\snew\s*\spassword:* %n\n *Retype\snew\s*\spassword:* %n\n
*password\supdated\ssuccessfully* .
unix password sync = Yes
syslog = 0
log file = /var/log/samba/log.%m
max log size = 1000
socket options = TCP_NODELAY IPTOS_DELAY
dns proxy = No
usershare allow guests = Yes
panic action = /usr/share/samba/panic-action %d
idmap config * : backend = tdb
[homes]
comment = Home Directories
valid users = %S
create mask = 0700
directory mask = 0700
browseable = No
[services]
comment = Services
path = /srv/samba
read only = No
create mask = 0664
directory mask = 0775
[www]
comment = WWW
path = /srv/samba/www
read only = No
create mask = 0664
directory mask = 0775
Thanks,
Bruno.
