Type=notify should really work. It activates a mechanism that systemd
will talk to the
daemon over a socket about its state (ready, shutting down, etc.),
rather than systemd
assuming that if a process is running that's it's actually ready.
Support for that has been
in PowerDNS Authoritative since 4.0 with 6988eae  it appears to me.
I could only find
this bug report about that it does not work with chroot settings .
I'd suggest to report it
as a bug if you did not enable chroot.
More on topic with your tests; please include more details about your
too. It's rather incomparable if you don't specify all (complex) MySQL
InnoDB pool size? InnoDB flush log settings? Pool warmed up or not?
Version? etc. etc. All potentially hugely important for the performance.
Other than that, really nice to see LMDB in action. :-)
