Dungeon Cave generator exstension loading issue

I’m using the Dungeon Generator extension, and specifically, I’m trying to generate a dungeon with these settings in the screenshot

The problem is that this generation takes a lot of time (even 30+ seconds!). Can you recommend reducing the time to a couple of seconds or if I’m doing something wrong? Consider that I have some other events in the list (like camera zoom, camera center x, y, and some player controls) but apart from this is just a prototype.

Thanks for the help!
