Peter, thank you for your suggestions. For the moment I will keep with the following settings, which provide satisfying latency and CPU usage:
-r 44100, -p64, with sDMA threshold=320 as per your suggestions, and CPU governor set to performance (1GHz). This way I can have 16ms in-out latency, with 15% CPU, no glitches and XRUNs (9% in jack, and 6% is the connection of system:{capture|playback} ports.
uname -a Linux debian-BB3 3.13.3-armv7-x10 #1 SMP Sat Feb 15 01:03:40 UTC 2014 armv7l GNU/Linux
In case I will need a lower latency I will try the USB soundcard suggested by Edgar.

I know this is working in realtime systems like in DSPs and non linux systems...
