Increase number of Queues

[spanugan]

Hi everyone,
In a recipe, how can I increase the number of queues to the device.
I see Queue Depth can be changed, is there a way to create multiple queues(threads) and have all of them pump reads/writes to the Device.
Thanks

It's not currently supported. Instead we gradually increase the number of threads automatically with requested QD: https://github.com/Microsoft/StorScore/blob/master/lib/DiskSpdRunner.pm#L93-L104

Just out of curiosity, what would you expect from multiple threads during a sequential test? Today we use DiskSpd "interlocked sequential" mode, which guarantees a strictly-sequential pattern of LBA accesses despite multiple threads:
