for any batch/offline processing. Double-buffering consume a lot of
memory, and causes additional memory copy traffic. So if you are just
reading from files, processing, and writing to another set of files,
double-buffering does not buy you anything. But for any use-case where you
are reading and/or writing to timing sensitive objects (ALSA, JACK,
rtnull), you'll benefit from double-buffering.
In ecasoundrc defaults, double-buffering is only disabeld in the 'nonrt'
profile and that applies only in he above case where there are no
real-time inputs nor outputs.
