Milliseconds, that is ;-)
I got a PIV 2.8 GHz Box with 1Gig RAM and envy24-Sound. Usually I run
jackd with 128 F/P and 44100 SR so i get 5.8 and can doo all the
desktopstuff (Mozilla, OO, GIMP etc) while i experiment with new
ams-patches or give some improvements to arrangements in ardour or test
new versions of Muse or RG.
If I find the time to work with sound only for 2-3 h I switch to 64 F/P
(gives 2.9ms) to have the whole stuff (Ardour, Midi, Synths,FX) working
at the same time. And to 32 F/P 96000 SR (0.66ms...) to do stuff with
just one synth and record it with qarecord...

Jackd runs all day and i usually get about 1-2 xruns/houre, especcially
at start up of ZynaddSubFX and caused by smaller bugs in rezound or
really insane patches for ams.

Still my edgy is not perfectly patched for audio, if I use 5 or more
complex instruments with ZynaddSubFX or load very complex ams-patches
with more the 4 voices polyphony(and have them played all at the same
time) I get lots of xruns.

So, as long as I do only "reasonable" stuff like playing 2-3
synthpatches plus working with Ardour and/or Muse and some sampleplaying
with specimen at the same time, it works perfectly well for me...

You got all the usual debian-stuff like apt and dpkg as known from
Debian, the biggest difference is the useraccount-concept. Like MacOSX
there is no active root-account and you (as the normal user) get
root-powers via sudo, if you need them.
Lots of generic deb-packages work OK in ubuntu, its own repos hold more
or less everything, one needs to do music-stuff (Ardour, RG, Muse, SND,
Rezound, Zynadd, AMS, OM, H2, PD, Csound, Specimen etc etc etc)
