This is correct. Any filesystem using the kernel's filesystem cache will do this, too.
For a long running, non-idle system, a good rule of thumb is that all RAM not being actively used is being used by evictable caching.
- zerd 5y agoA colleague who was used to other UNIXes was transitioning to Linux for a database. He saw in free that used was more at more than 90%, so he added more ram. But to his surprise it was still using 90%! He kept adding ram. I told him that he had to subtract the buffer and cached values (this was before free had the Available column).
