Using RAM for "caching" sounds extremely wasteful. There could be applications that want to use it for something more useful than a 1% performance improvement.

Caching is way more impactful than a 1% speed up. It is hard to know exactly, because it is impossible to disable on most modern operating systems, but I wouldn’t be surprised if it were an order of magnitude improvement in some situations.

By the way, caching doesn’t prevent RAM for being used by applications. If an application wants more memory, the os can always just evict some of the cache.
