Reduce config load and increase priority

[vvanglro]

In the new process manager mode, if I pass in the wrong app, the process keeps restarting.

After I read the config.load() call logic of the entire project code, I think I can reduce unnecessary calls in the code and increase the priority, that is, continue to create sockets and process management after the load is completed.

@Kludex What do you think?

If you can show me some code, it would be nice.
