Disabling services to free up resources for OwnCloud.

In the general interest of improving performance I decided to disable services that aren't needed:

I installed rcconf: 
sudo apt-get install rcconf

Started rcconf up:
sudo rcconf

Disabled the following:

• alsa-utils
• anacron
• avahi-daemon
• clamav-freshclam (virus scanning for me happens on my sonicwall gatewall)
• gdm
• cups (if you don't need print services)
