According to your comment if I understand correctly, you are basically asking "how the boosted monster is in comparision to normals ones, in a matter of loot, exp and respawn rate?".
The answer is double exp, loot and also respawn.
A boosted creature yields double XP, double loot and has its respawn rate increased by 2x till the next server save.
