[Bug 2056697] Re: Ubuntu Studio should prefer realtime kernel

[Brent Baccala]

OK, fine, all valid points.

I'm not so sure about the "placebo effect", though.

I played the same piece a dozen times on my MIDI keyboard in various
configurations, with the following results:

realtime alsa: xruns 0, 0, 0
realtime jack: xruns 11, 0, 0
lowlatency jack: xruns 25, 5, 5, 6, 8

Admittedly, it was a small test, but I made some effort to actually test
it and concluded that I was getting better performance from the realtime
kernel.

I think some more investigation is required.

Title:
  Ubuntu Studio should prefer realtime kernel

Status in os-prober package in Ubuntu:
  Won't Fix

Bug description:
  Now that Ubuntu has released a realtime kernel, I suggest that Ubuntu
  Studio's boot preference should be:

  1. realtime
  2. lowlatency
  3. default

  I've been running the realtime kernel for a week, haven't had any
  problems with it, and am seeing noticeably fewer xruns in Ardour.
