I never tried 512 Syncs per second, nor do I see any reason to run
such a high rate.  What is that supposed to achieve?

In general, if you want to handle one event every 1.9 milliseconds,
then you must be running RT_PREEMPT with ptp4l at sufficiently high
priority.  Standard Linux will exhibit scheduling latencies well above
2 milliseconds.
