Is there a way to have diagnosis about this from Ardour's side ?  At
the system level 'free' reports 6GB out of 15GB free, 8GB in use.  Does
this mean that the memory access/workability was checked at boot ? I
would tend to think so, but not certain.

Ardour (Mixbus 32C) does not complain about memory or anything else at
startup so I presume it is satisfied.  I have yet to see an option in
the configuration about buffer sizes - if there is such I will try to
put other values.
