Redmi note 9s 4/64 bad ram management (stock rom)

[pablomolina49]

Hello guys
I own a redmi note 9s (curtana) of 4 gigs of ram, when I bought it, I thought that 4 gigs of ram would be enough for the use that I give it (spotify, twitter, whatsapp and instagram), but this device is terribly optimized in therms of ram managment. Even the redmi note 9(4 gigs too) that my mother owns keep much more apps in background and opens it faster. I know that this forum is not the place to complan about that, but if I install xiaomi.eu, it will improve my multitasking enough?
In this video is visible the diference between 4 and 6 gigs and same processor:

I dont understand anything in the Video. But based on your complains and the Screenshot I can tell you that Android is based on Linux and therefore it's important to keep in mind that unused RAM is wasted ram.
