Line 92:
What is it about: Controls how far away spawned mobs can be.
We are going to lower how frequently and how many mobs can spawn, so lowering this will create the illusion we haven't lowered mob spawns.
Default: 4
I am using it in: 3
Line 94, 95 and 96:
What is it about: Entities outside these ranges will be ticked less frequently. Animals generally don't need much. "misc" is stuff like item drops. Setting it to 1 may prevent item drops from i.e. flowing in water.
Default: animals:32 monsters:32 misc:16
I am using it in: animals:6 monsters:24 misc:2
Line 104, 105 and 106:
What is it about: This will make hoppers tick three times slower, but move three items at a time. This can break some vanilla behavior, especially stuff like redstone clocks depending on hopper times. Can be a major player in hopper lag.
Default: transfer:8 check:8 amount:1
I am using it in: transfer:24 check:24 amount:3
Line 110:
What is it about: How many times an entity can collide with per tick. Setting this to 2 usually has no implications. Helps a lot with mob farms.
Default: 8
I am using it in: 2
Line 126, 127 and 128:
What is it about: The item merger is a powerful way to prevent item drop lag (no more ClearLag!). Setting the item property to 3.5 means items in a radius of 3.5 blocks will be "merged" into one stack of items. Exp has no real downside to merging at a high radius.
Default: item:2.5 exp:3.0
I am using it in: item:3.5 exp:6.0
Line 131:
What is it about: How many chunks are sent to the player.
Default: 10
I am using it in: 4

Line 25, 26, 27, 28 and 29:
What is it about: These values are more complicated than just "allowed mobs per player", but they do something in that direction. Setting these lower will grant less maximum mobs spawning around players. The more players you have, the lower you can safely set this.
Default: monsters:70 animals:15 water-animals:5 ambient:15
I am using it in: monsters:65 animals:15 water-animals:3 ambient:4
Line 30, 31 and 32:
What is it about: This feature is disabled by default (load-threshold is zero) for no reason, as far as I can tell.
This option will unload chunks that aren't needed (outside players' view distance), freeing up memory and potential CPU resources.
Default: period-in-ticks:600 load-threshold:0
I am using it in: period-in-ticks:300 load-threshold:300
Line 35:
What is it about: Controls how often the server should attempt spawning a hostile mob. This accounts for the entire server, not per-player. Setting this high will drastically lower the amount of monsters spawning. I generally recommend 2 unless a server has lots of lag coming from the mobSpawn function or just have too many monsters in general.
Default: 1
I am using it in: 2
