reduced number at birth of mobs

Hello, I would like to report a problem that I had and that several friends of mine also had, a good time and my friends who play in Minecraft Java Edition and we decided to play Minecraft MCPE (MCPE) to know this version, install the game and get started to reproduce a big problem in relation to the amount of monsters, which has no mcpe and very small in relation to java, walking at night on the map without problems, because there were few mobs and everyone is very scattered, if applicable the number of mobs , that way or the game would be more like Java and players use a much better gaming experience. thanks for listening.
