Filestreams is needed to optimise concurrent *ingest* of data,
not playout.
i.e. if you are ingesting multiple real-time streams of data at the
same time as you are playing out real-time streams and you area
missing playout deadlines (i.e. dropping frames) due to sub-optimal
data layout, then it might help you.....

It went into .22 so you should have it.

The allocator behaviour is changed by the mount option "-o filestreams".
