Why R uses so much memory ? Probably
Technically, the bottleneck describes how the information transfer might be slower than the processing speed, but in R, RAM and SSD transfer is the most relevant example.
The problem with R is the amount of RAM it needed to store all the object you need for the analysis. I watched a Veritasium video about the von Neumann Bottleneck and realize that exactly the term needed to explain this concept.
I am unsure if the designer of R wanted R to do this, but for myself that wants to make sure things are easier to manage, this is exactly the thing that I would do :P
