Can anyone explain these console commands?

Hey, i’, hosting my own rust server now, and i’d like to increase the respawn rate for ores/tress/barrels.

I found the following commands:

-spawn.min_rate 0.1
-spawn.max_rate 1

-spawn.min_density 0.1
-spawn.max_density 1

So what should i change these values to? min/max_rate to 1 or both to 0.1 ? There’s no explanation for these values.

I believe this was for Legacy, but should be fine using in Main:
