Hi Julien,

sorry for the delay in reply.

Yes, this is because the Config is restarted again on each config
change. This is an implementatino bug and probably the authors
did not know better at that time (read 5 years ago). Though on
that time the Config was not that slow because there where 2000
less packages and a handful of options less as well.

The slowness is why we already started accelerating the worst
code-pathes with Lua code.

We already have on our Roadmap to rewrite the remaining parts,
including a more inteligent implementation not restarting the
whole Config process again after every Config change:

I hope you do not need to Configure too much, and can live with
the not super-fast Config for a while. Any help reworking the
Config to not restart itself on every change is very appreciated!
