Realtime kernel info

From Rivendell Wiki

In order to get good performance with audio applications on linux, the system/kernel should be tuned for better realtime performance. This is especially true when using ALSA (or JACK with ALSA) sound devices. The Audioscience sound cards have high quality hardware design and large buffers that make realtime tunning less critical.

There are several ways to get better performance from a linux kernel. They include:

• rtlimits-enabled pam
• realtime-lsm (older approach)
