Making freebsd - pcbsd faster by changing the interrupt requests

[Hans Ruhe]

Hello everybody,

I am testing for PCBSD primarily but I am also testing with a hifi
journalist, tube amplifier designer. This is the website:
http://www.audio-creative.nl/

Mind you it is mostly in Dutch but some parts are in English. They recently
started to sell kits like a dac and a tube phono amplifier.
Mind you this guy has a University degree in electronics and the firm he
works for make parts for ASML which sells machines for Intel, Samsung etc
to bake their processors. So it is a very high level of knowledge of
electronics.

Always looking for better sound, 2 months ago I came upon Ubuntu Studio,
which projects uses real time latency and changing interrupt requests to
make it faster and also to have those requests dealing with audio and
movies a privilege above other ones.

I am not that far that I exactly know what they do, but the fiddle in the
kernel for that :-)
Also I am not a developer ( i bought myself a Raspberry Pi to make the
first steps though).

This is only an idea, but would it be possible to do such a thing for
freebsd and pcbsd as well ?

I tested Ubuntu Studio with the use of Audacious and I could really hear a
difference. I have a 3 way loudspeakersystem and a EL84 tube amplifier in
Class A (yes it uses some more electricity but it really pays of enjoying
music a lot more ;-)

Best regards,
Hans
