- standard SMB instalation
- slow read and write sorted
- example smb.conf
1. Installing samba:
cd /usr/ports/net/samba3; make install clean
- copy and adjust the configuration details:
cp /usr/local/etc/smb.conf.sample /usr/local/etc/smb.conf
check your configuration:
testparm
In my case samba was very slow with a speed around 1,3 Mbyte/s.
- sftp copy has had speen around 6 Mbyte/s
Old server with 32-bit FreeBSD 6.4 and Samba 2.7 has had speed 22 Mbytes/s with Intel(R) PRO/1000 Network cards.
After some research I found that I need AIO_SUPPORT and slightly adjust my configuration.
2. Improving speed
AIO_SUPPORT:
kldload aio
and add this line to /boot/loader.conf
aio_load="YES"
3. Adding those lines to smb.conf
use sendfile=true
aio read size = 16384
aio write size = 16384
aio write behind = true
4. samba configuration file (example smb.conf)
[root@server ~]# testparm

Now is Samba File Server quicker - 8,7 Mbytes/s instead of 1,3 Mbyte/s.
There is not set up printing at this example.
Next upgrade will be slow data switch with new Intel(R) PRO/1000 Network card. I am expecting speed is around 22 Mbyte/s or 1GB file/min.

PS. I did try change sysctl with recomended values and had bit slower connection.
