IOmeter - how to interpret queue depths

[tigweld0101]

I have done an IOmeter configuration. I saw 4 workers was popular so I have that. I also have # of IO's on the config tab set to 2-64 exponential scaling. When results come out, I see the QD64 results in the column but are those 64 really or are they QD64 x 4 workers = QD256

Thanks in advance gurus.

It is per worker. So QD256. I suggest setting workers = physical cores not hyper-threads.
