An simple test to measure this reliably is to strip down the legacy sysv
init script to the start up command only and have a strip down unit file to
the startup command only.
Then time the startup of either.
Why? The current numbers show that the service file is _slower_ even
when the old init script is supposedly doing much more work in shell.
If anything, stripping the unessential parts should make the service
file _even slower_ in relative terms.
Yes. The unit file is already stripped down: it does nothing except
"pg_ctl start". The init script had accumulated a whole lot of
perhaps-unnecessary sanity-checking, which frankly I'd rather have kept
but the systemd mantra seems to be "no shell scripting" so I didn't.
Michal's numbers look pretty damning, and I find it remarkable that the
systemd advocates seem to have managed not to read them, let alone admit
Don't confuse we with facts! I've already made up my mind! ;-)
that they suggest something's seriously wrong.
