The Fedora Musicians Guide has a good topic on Real-Time and Low-Latency:
http://docs.fedoraproject.org/en-US/Fedora_Draft_Documentation/0.1/html/...
My understanding:

* A Real-Time kernel will give you more consistent, reliable latency.

   - But not necessarily lower latency

* Useful, proven, RT features migrate into the main kernel.

   - So use the RT patches to test and prove them.

* Current main kernels give reasonable performance for most musicians.

   - Your mileage may vary, if you get some annoying x-runs use the RT patch.

   - Sound travels ~1 foot per millisecond, 8 feet from the speaker =

8ms latency
