Instead of a simple "Least Recently Used" algorithm, ZFS uses the ARC to balance frequently and recently used data. Tuning vfs.zfs.arc_max is essential for ensuring your system doesn't starve other processes of RAM.
Mastery begins with understanding how ZFS interacts with your hardware. Unlike standard filesystems, ZFS integrates the volume manager, requiring precise control over the physical layout. free betterbsd mastery advanced zfs pdf
Adding a dedicated SLOG (ZFS Intent Log) on a low-latency SSD can transform synchronous write performance, while the L2ARC extends your read cache to fast flash media. Instead of a simple "Least Recently Used" algorithm,
One of the most complex chapters in ZFS mastery is performance orchestration. ZFS integrates the volume manager
