ZFS ZFS performance recommandation

Hi everyone,

I'm not sure in it is the best place for ask this, so let me know.

Right now I'm using jail on my system and it's setup on vnode memory disk (mdconfig). It works but it is not really good in term of performance.
I wanted to put my jails directly on ZFS storage instead using memory disk. I'm assume it will be way better.
But I also saw that it is possible to have a special type of dataset ("Volumes" to be exposed as a block device ).

Is there any best choice in term of io access and performance in general by using jail on zfs directly, or jail using "Volumes" on ZFS.


Regards,
Thibault
 
Best way to find out is just use a ZFS dataset for your jail and check it's performance. Adding a zvol layer will add complexity. If you want the jail to manage datasets, you can delegate them to the jail.
