This one is IMO better worded, so just use that.

ZFS Performance Tips
~~~~~~~~~~~~~~~~~~~~
ZFS uses a lot of memory, so it is best to add additional RAM if you
want to use ZFS. A good calculation is 4GB plus 1GB RAM for each TB
ZFS works best with a lot of memory. If you intend to use ZFS make sure to have
enough RAM available for it. A good calculation is 4GB plus 1GB RAM for each TB
RAW disk space.
ZFS also provides the ability to use a fast SSD drive as write cache. The
write cache is called the ZFS Intent Log (ZIL). You can add that after
the installation using the following command:
zpool add <pool-name> log </dev/path_to_fast_ssd>
ZFS can use a dedicated drive as write cache, called the ZFS Intent Log (ZIL).
Use a fast drive (SSD) for it. It can be added after installation with the
following command:
---
# zpool add <pool-name> log </dev/path_to_fast_ssd>
