Afaik there is no maintained RT kernel PPA repository. Alessio Igor
Bogani used to maintain a PPA and Trisquel did a stab at it, same goes
for KXStudio. It's simply a lot of work.

In my case I have a selection of projects that I try to keep pace with and
they are pulled to a special folder. ex.
/home/<user>/code/
These days I rarely have dependency issues even on the most cutting edge
dev repos but I run with debian unstable/sid.

Are there any real benefits to building software
on your local machine
vs installing binaries, in this case all largely Ubuntu
based?
There are some things you just can't get with ubuntu (probably debian is
not much different). Linux Sampler, ffmpeg, cdrecord, GCDMaster and non*
are a few that come to mind. If you follow this list at all, There is a
time lag from when new stuff comes out and when it appears on Ubuntu, so
things people announce here are not available for some time. I've finally got this old mackbook 1,1 (Nov
2006 white 13") running
linux audio with comparable results to its native OSx
10.6. Whatevah
Snow LeopRd was. Set up dual boot.
Cool.
I've removed lots of software I won't use
on it like cups, samba, misc
daemons nibbling away at memory n cycles. Xfce
desktop.
I could remove most of those for even my desktop use :)
Can I gain any performance from building certain
software on the
machine? Mostly, I guess low or more efficient resource usage.
Kernel
included. Right now running SMP lowtatency kernel. I'm still if the
belief that a RT kernel would be better but obviously in the deb world,
not so many available.
There is a RT kernel in the Ubuntu repos somewhere (fairly new and
private, but maitained) I don't think it is there for the last LTS and I
couldn't find it with casual googling.
Most of the kernel is modules so kernel bloat from trying to support
everything is not much of a problem... though the kernels do seem to be
much bigger than when I started and they fit on a floppy.
my almost new i5 is so much faster than the old p4 (4 cores instead of
one doesn't hurt either) and has 4 times the ram. So that it is quite
hard for me to notice extra memory/cpu use. I can run 16/2 with my old
ice1712 audio IF with no xruns on the lowlatency kernel, so it is kinda
hard to spend much time worrying about a RT kernel.
