Regarding the ARC, is zfs not as efficient about evicting the cache as, say, ext4? With ext4 I've never had to worry about it consuming as much memory as it pleases.
Thanks for the tips!
- patrickg_zill 13y agoMy layman's understanding: under Linux the ARC is not integrated into the usual Linux caches which are unified and which the kernel understands. So basically the ZFS ARC is a separate chunk of RAM, which can grow and grow (thus you need to limit it) and it won't be evicted as perfectly as the kernel would evict stuff cached on xfs or ext4 filesystem.
- smilliken 13y agoAh, that makes sense. Thanks for the explanation.
