+Only applicable for purpur.

+<h4>use-alternate-keepalive</h4>
+<b>default:</b> false<br>
+<b>optimized:</b> true<br>
+<b>explanation:</b><br>
+Alternate system for keepalive packets so players with bad connection don't get timed out as often.
+
+<h4>dont-send-useless-entity-packets</h4>
+<b>default:</b> false<br>
+<b>optimized:</b> true<br>
+<b>explanation:</b><br>
+Prevent the server from sending empty position change packets (by default server sends move packet for each entity
+even if the entity hasn't moved)
+
+<h4>gameplay-mechanics.player.teleport-if-outside-border</h4>
+<b>default:</b> false<br>
+<b>optimized:</b> true<br>
+<b>explanation:</b><br>
+Teleport the player to the world spawn if they happen to be outside of the world border. This will help, because vanilla
+world border is bypassable and the damage it does to the player can be mitigated.
+
+<h4>gameplay-mechanics.player.entities-can-use-portals</h4>
+<b>default:</b> true<br>
+<b>optimized:</b> false<br>
+<b>explanation:</b><br>
+Disables portal usage of all entities besides player. This potentially fixes a dupe* and prevents entities changing 
+worlds loading chunks on main thread.<br>
+*more sources needed.
+
+<h4>mobs.dolphin.disable-treasure-searching</h4>
+<b>default:</b> false<br>
+<b>optimized:</b> true<br>
+<b>explanation:</b><br>
+Prevents dolphins from performing structure search similiar to the one that treasure maps do.
+
+<h4>mobs.zombie.aggressive-towards-villager-when-lagging</h4>
+<b>default:</b> false<br>
+<b>optimized:</b> true<br>
+<b>explanation:</b><br>
+Zombies stop targetting villagers when tps is under lag treshold. This saves the server precious time of calculating 
+paths for zombies that are not targetting players.
