That’s a common argument; but in Linux these are reported differently. I believe it is the same in windows and MacOS too. So “used ram” from the OS perspective cannot be reused as filesystem caches. I doubt they’re increasing performance either as the overall performance of such a system is so low. it’s also hard to argue increased performance when your app could have instead fit in L3 cache.
