The test case was build 38, Solaris 11, a 2 GB file, initially created with 1 MB SW, and a recsize of 8 KB, on a pool with two raid-z 5+1, accessed with 24 threads of 8 KB RW, for 500,000 ops or 40 seconds which ever came first. The result at the pool level was 78% of the operations were RR, all overhead.
