Hi epicurean,Hi Zos,
Can you explain to a noob like me what your recommended actions actually do to improve a SOHO mysql setup like mine?
for beginners (as you wrote you are) there's no need to change anything of your configuration. My notes about mysql with ZFS doesn't really matter for a small SOHO installation, it will work perfectly without any changes.
But if you really want to improve your MySQL setup, first thing is to become acquainted with the console (it is not always practicable to work with napp-it's cmd box) and further on just follow the steps described in my post.
