performance.
Are you sure about the single-threading being controlled by --sync ?
I've never seen this mentioned before.
AFAIK, with --sync jackd2 writes the outputs to the driver when
all clients have run, same as jackd1. Without --sync it writes
the outputs of the previous cycle before any clients run,
resulting in one period more latency but a bit more resilience
agains xruns.
