Do you have any details of what contributes to the start time in
your case?

In general, nginx trades start time to faster operation once
started, and trying to build minimal hash is an example of this
practice. If it results in unacceptable start times we certainly
should optimize it, though I don't think I've seen such cases in
my practice.

Most time-consuming things during start I've seen so far are:

- multiple DNS names in the configuration and slow system
resolver;

- multiple SSL certificates;

- very large geo{} maps.
