There is a lot of stuff on the Internet and FreeBSD handbook. What
NetBSD is missing is how to tune it for old and low memory systems, see
the following https://www.freebsd.org/doc/handbook/zfs-advanced.html

Also, not clear if NetBSD ZFS supports TRIM for SSDs, and if yes how to
enable or disable it. Are there any sysctl variables I can set (I looked
but didn't find any), or any other method of configuring such ZFS
options.
