I can only answer some of these questions. The 1010s will have
slightly lower latency. Mine runs at 16/2,
Len, what about the sampling frequency you have set running at 16/2?
48k, synced to my 48K s/pdif preamp as happens.

- /etc/default/rtirq has:
RTIRQ_NAME_LIST="rtc snd_ice1712 snd usb i8042"
why not just: RTIRQ_NAME_LIST="rtc snd usb i8042" ?
Because I want my audio card ICE1712 to be higher priority than my MIDI
card which also has an audio portion (snd_ens1370) Really I could (and
should remove USB from the list as there is nothing on USB that needs to
be prioritized. The stock rtirq tries to be rightish no matter what audio
IF the user plugs in, but boosting ones mouse priority above the hard
drive and ethernet does not really make sense :)
I do the same thing on my netbook by setting "usb3 snd usb" to push the
usb3 port (where my audio IF sits with a clear irq) to a higher priority
than the SD reader, internal camera and whatever else Acer decided to hook
up to USB internally. The snd in there is for internal audio when I use
that. (generally output only)

- I turn off cron while running low latency use.
uhm... Interesting... I'll try this...
Cron runs at maximum niceness, but checking for new SW does a lot of disk
read/write and network traffic. Turning cron off seems to get rid of some
of those odd spaced spurious xruns. Some people turn off auto updates
instead, and do those manually. Cups is not as bad as the win print
servers used to be (everything stopped while the windows system printed a
page) but I don't run that either. When I was running the P4 with low
memory I tried to think of anything that might give trouble and went for
the quietest system I could.
I have an app that
does this all together for me:

I prefer using a script which (should :-) turn my "desktop system" into a "RT
DAW Audio System": I can edit the script so I can decide exactly what to
do...
The app I use is a script for the most part (actually a collection of
scripts) and can change everything on the fly. But it is jackdbus centric
which some people just don't like. I could probably make it jackd(1/2) if
I really felt like it, but I don't :) No solid reason, just my bent.
