If you mean by "delay when restarts" => "before shutdown", it may take up to
three (3) minutes by default before Windows times out preshutdown services, then
it may take up to two (2) minutes by default before Windows times out service
process shutdown.
Is that not better than abruptly terminating an sshd session, or abandoning
sending a large email?
I would expect UPS shutdown handlers to do whatever is required to expedite a
speedy shutdown within a a few tens of ms/a mains power cycle or two.
