Paul, does ardour allow to specify the size of the
per-track-buffers
you use for disk streaming, if yes perhaps you should add this as an
option since it's handy for the user having the possibility to
increase the default values to achieve optimal track count.
yes, you can control both the per-track buffer size and the chunk size
used for disk i/o. there's no GUI for this at the present time, but
the XML file is transparent.
