I'm currently running badblocks on 24 x 10TB SAS3 HDDs and seemingly running into a bottleneck that is limiting me to 4GB/s in aggregate io (see screenshot below). When I run badblocks on just a select few disks at a time I get upwards of 250+ MB/s per drive. The HBA is connected to a PCIe 3.0 x8 slot on a Supermicro X11SCH motherboard.
Any ideas why I'm only hitting about half the theoretical bandwidth of the PCIe slot? Is the chipset limiting me?
