NFS writes (especially for lots of small files) to omniOS *really* benefit

You could remove the cache from the pool, carve of an 8GB chunk for ZIL on
each and the rest for L2arc if you want that.
then add a mirrored zil using the 8GB chunks and the other partition for
l2arc
An SSD zil helps with metadata update absorption and small files writes that
are synchronous over NFS. A lot. (that's my experience)
It looks like that is what he did but it looks like an error was made
in that a spinning disk may have been added as a log drive
(c0t55CD2E414EC0FF43d0s0) rather than an SSD as was intended.
