ZFS and a spare SSD: ZIL or L2ARC?

I have a FreeBSD server with a 4TB ZRAID1 and 16GiB RAM; it's also 
hosting a Windows 7 with SQL Server through bhyve.

Now I've just got hold of a spare SSD and, although the box performance 
is adequate, I'd like to see if it can boost it.
Should I configure it as L2ARC? ZIL? Both?

Which will benefit the bhyve VM more?

  bye & Thanks
