I have been installed ES 5.0. But it consumes too much ram above 2Gb, While older ones consume around 200Mb. Can you guys help me explain for me? Is it normal?

RAM or heap?  
How are you measuring it?

I use systemctrl to view status and top command. I run on Ubuntu 16.04.

There are differences here, I assume you are talking about RAM not heap.
