But myself, i have been able to improve latency and performance dramatically, by not using pre-packaged rt-kernels. Once users get more advanced in their understanding, there are a number of things you can tune in the kernel.

You do that stuff on your own time! Artists have always made their money live, and through merchandise. Record sales go into the Label's pockets for the most part. jordan -- To unsubscribe from this list: send the line "unsubscribe linux-rt-users" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
