Thanks for your tool, @jgreco! It helped me pinpoint a bottleneck in my setup – a single connector between the HBA and a 24-port backplane (BPN-SAS3-846EL2). The issue was resolved by connecting two SFF-8643 cables from the SAS3008/9300-8i running firmware 16.00.12.00 to the primary and secondary expander ports on the same backplane. This resolved the "--SLOW--" indication in the parallel array read test upon retesting. For reference, this 24-port backplane has 16x 20TB Seagate Exos X20 ST20000NM007D-3DJ103 SATA 6Gb/s Standard Model FastFormat (512e/4Kn) disks attached to it.

The parallel stress test is actually one of the main goals of the tool, and is meant to bring your awareness to bottleneck issues that might otherwise have gone unnoticed. Funny that all these years later with completely different bus topologies that we still have these problems...
Great tool. Definitely it gives quite some level of confidence.
Just be ready, it might take quite some time before it is completed.
Just as a reference: 10x12TB set of disks on Xeon system was up and running for ~7 days before was completed.
But then there is a good understanding about the setup.
Thanks
Thanks for this great tool.
