OK. When I tried it though, I was logged in as root.

I have now tried 256 and it is quite good. Had to set it using
qjackctl and did another reboot though, which is something I do not
like to do as it goes against all that Linux systems stands for eg.
being able to kill a process and restart it easily.

Thanks. I'll take a look at he links you provided. For now 256 seems
OK.
I will have to look into this a bit further since I have to compile
jackd from upstream. The current one in this system prevents Ardour
from exporting audio.
