Default spawn rates are off the charts, my players all ragequit.

First I would recommend the default spawn rates be turned way way down they are very overwhelming and the server is struggling to keep up with all of the entities.

I am reading about the spawn configuration, but it's so powerful it makes it hard to use.

Is there a global spawn rate config, or do I need to edit every file to adjust spawn rates?

There are 9 in this picture which doesn't count the ones that popped out when killing the ones there.
