Because microprocessors are so fast, computer architecture design has evolved towards adding various levels of caching between compute units and the main memory, in order to hide the latency of bringing the bits to the brains. This avoids thrashing caches too much for B and evens out the pressure on the L3 caches of the machine.

The ZFS Adapative Replacement Cache (ARC) is the main memory cache for the file system. The arc_reclaim_thread periodically runs arc_adjust() to evict memory from the cache to keep it from growing too large, and to maintain a threshold of free memory that applications can quickly use. I worked on this code back at Sun.
