Look at your cache age. It's very low, meaning that you are not serving data out of memory, only directly from disk. As the cache age does down, see that your network out numbers go down as well.
When your filer gets full, it isn't able to find contiguous space to write data to (thus write 'anywhere'), so it starts breaking things up and you lose temporal locality, which eliminates the benefits of Netapp's read-ahead caching mechanism, thus low cache ages and poor performance. That's probably what's happening.
You should think about a wafl_scan reallocate when the system utiliziation goes down, or getting a bunch of data off the box.
