In Enhanced Multi-Packet Send (eMPW), entire packet data is prefetched to LLC if it isn't inlined. Even though this helps reducing jitter when HW fetches data by DMA, this can thresh the LLC with evicting precious data. And if the size of queue is large and there are many queues, this might not be effective. Also, if application runs on a remote node from the PCIe link, it may not be helpful and can even cause bad results.
