Can't really help you but here is couple of notes:
1. iostat -x output seems to be even more informative for disk I/O
2. Despite large amount of RAM (8GB) your ZFS ARC size stays at its minimum value
near just 200MB.  Not sure if this plays significant role in the performance
issue, but perhaps something to look at.
