Anonymous Page Cache gives backstores to anonymous pages. For those dynamically generated but rarely used/modified data structures, it tries to save them on disk and load them on demand. The idea is similar to a swap file except:
- It's in userland and requires no special privilege.
- The timing and scope to save/swap out is determined by programmer, rather than OS.
