-To use ZFS, at least 1 GB of memory is recommended (for all architectures) but more is helpful as ZFS needs *lots* of memory.  Depending on your workload, it may be possible to use ZFS on systems with less memory, but it requires careful tuning to avoid panics from memory exhaustion in the kernel.+[[https://openzfs.github.io/openzfs-docs/Project%20and%20Community/FAQ.html#performance-considerations|OpenZFS documentation recommends a minimum of 2GB of memory for ZFS]]; additional memory is //strongly recommended when the compression and deduplication features are enabled//.

 A 64-bit system is preferred due to its larger address space and better performance on 64-bit variables, which are used extensively by ZFS. 32-bit systems are supported though, with sufficient tuning. A 64-bit system is preferred due to its larger address space and better performance on 64-bit variables, which are used extensively by ZFS. 32-bit systems are supported though, with sufficient tuning.
