> We're probably focusing a bit too much on random read/write times when there is no evidence or rationale for thinking that the Mixed Workload phase is random read/write. Dave threw that in for reasons which are unclear. There is no evidence from the iozone output, or from its man page, to support the assertion.

From what I can tell by reading the source code, it is a mix where half of the threads are doing random reads, and half of the threads are doing random writes.
