Advanced Linux Configuration
JACK and Ardour will run quite a bit better if your Linux operating system is properly configured for Real-time operation. Ardour will function properly without such configuration, but you may suffer 'glitching' or 'stuttering' of the audio under some circumstances. Distributions of Linux that automatically allow Real-time operation can be downloaded for free, including Ubuntu Studio and 64 Studio and this is the simplest method to get Real-time operation for Ardour.
Setting up a Real-time system for other distributions is beyond the scope of this manual, as it involves recompiling your Linux kernel as well as setting up some specific configuration files. The following resources may be useful to the interested reader:
