AFAIR from old PCI times (seems that PCIe is only extension to PCI) reading from PCI device to memory was much slower than writing from PCI device to memory - if there is chance to make PCIe device transaction initiatior and order that PCIe device will write to system memory should IMHO faster than reading from device.
