That article takes a system with 2GB ram as example. For a modern system that is pretty unrealistic, even Laptops have more. My system has 12. I missed the mention of zram. Zram can create ramdisks, and compress them. It can create a compressed swapdisk in ram, basically making your ram last longer in case you really run out of memory. In my experience that is a good alternative to having a bit of swapspace as reserve, as the article recommends.
