Computers that have less than 2 GiB of memory run ZFS slowly. 4 GiB of memory is recommended for normal performance in basic workloads. If you wish to use deduplication, you will need [massive amounts of RAM](http://wiki.freebsd.org/ZFSTuningGuide#Deduplication). Enabling deduplication is a permanent change that cannot be easily reverted.
