At FOSDEM'19 Allan Jude talked about ZFS Caching.

Short introduction to ZFS and what Copy-on-Write means.

In-depth explanation how caching works, about compressed ARC and why "free RAM is wasted RAM". Why we want to tune ARC for different use cases (fileservers, block storage, databases, hypervisor). In the Q&A Allan talks about the upcoming ZSTD compression for ZFS among a lot of interesting Questions.

A definiteve must have seen not only for ZFS-starters.
