There are often more statistics available than you realize or have been documented , which may certainly be true with the ARC. These tracing techniques are also applicable to any kernel subsystem. Main memory is balanced between these algorithms based on their performance, which is known by maintaining extra metadata in main memory to see how each algorithm would perform if it ruled all of memory. These changes include the ability to lock pages, vary the size of the cache, and to cache buffers of different sizes. This is a simplification to convey the basic principle. This can be understood from a lifecycle of an ARC buffer: on the first access, it is created and moved to the head of the MRU list. On the second access, it is moved to the head of the MFU list. On the third access, it moves back to the start of the MFU list.
