Configuration

WIP; samba is slow with the default config

# Test smb.conf
testparm

rlimit_max will likely need to be increased.

vi /etc/security/limits.conf

# add the following line
* - nofile 16384

# reboot and rerun testparm

Disable Printers

# Add to /etc/samba/smb.conf

   load printers = no
   printing = bsd
   printcap name = /dev/null
   show add printer wizard = no
   disable spoolss = yes

Performance Tuning

• https://wiki.samba.org/index.php/Linux_Performance
• http://www.samba.org/samba/docs/man/Samba-HOWTO-Collection/speed.html
• http://www.eggplant.pro/blog/faster-samba-smb-cifs-share-performance/
• enable jumbo frames on server
• tweak osx client delayed_ack param

# Add to /etc/samba/smb.conf

Test

Test speed with rsync or pv: http://askubuntu.com/questions/17275/progress-and-speed-with-cp

# Example for samba "backup" folder mounted on OSX
rsync -av --progress [SOURCE_FILE] /Volumes/backup
