Out of curiosity, if you disable the zil through the evil zfs tuning
wiki mechanisms (diagnostic purposes only), does it dramatically help?
If not, there's something else going on, if yes, it could be that the
l2arc and zil are interfering with each other (I could imagine that the
l2arc is causing a lot of need for erasing of blocks on the SSD which
could be dramatically slowing things down. I haven't been following the
implementation of TRIM support and any outstanding issues)

It's an SSD. It just has a long name because it's in a hotswap sled
instead being inside the chassis.

Lee,
Just in case you did not see my follow-up post, it looks like
there is
an error in your pool configuration that a large spinning disk was
added as a log device rather than a SSD as was intended. Luckily it
should be possible to fix this without restarting the pool from
scratch.
