This question already has an answer here:
I have a program in python which takes lots of ram. My server has 16gb of ram, but when the program reaches ~8gb of ram, the os starts writing on disk which breaks performance.
I want the process I'm running to use all the available RAM. Why does it seem limited?
I'm running a pure debian os.
