Short Name: Maximum In-Flight Read Requests

Property of niHSDIO

Specifies the number of memory reads on the PCI Express bus at the same time. In general, the larger this number, the more efficiently the NI device uses the bus because the system has more information about the device needs. A larger number of in-flight read requests means that more read requests are then expected by the system, so it can allocate bandwidth appropriately. Decrease the number of in-flight read requests when your application is using other hardware that is not as efficient as the NI device. The amount of reduction depends on the behavior of the other hardware.
