I've used 8K IO sizes for all the stage one tests - I know I might get it to go faster with a larger size, but I like to know how well systems will do when I treat them badly! The Stage_1_Ops_thru_run is interesting. 2000+ ops/sec on random writes, 5000 on reads.
This seems like rather low random write performance. My 12-drive array of rotating rust obtains 3708.89 ops/sec. In order to be effective, it seems that a synchronous write log should perform considerably better than the backing store.
