ZFS expects to have a huge cache, and defaults to 50% of memory, separate to any other fs cache. For advanced features, it requires a certain amount of cache per TB of storage. For single-disk non-checksummed, non-deduplicated storage, it's a lot of wasted code that a device with a "mere" gigabyte of RAM doesn't need. So APFS hits most of their needs: volume management + journal + better disk layout for SSD. |
