+| Description                    | The performance of an DPDK application may vary across executions of an              |
+|                                | application due to a varying number of TLB misses depending on the location of       |

+|                                | This situation occurs on rare occasions.                                             |

++--------------------------------+--------------------------------------------------------------------------------------+
+| Implication                    | Occasionally, relatively poor performance of DPDK applications is encountered.       |
+|                                |                                                                                      |

+| Resolution/ Workaround         | Using 1 GB pages results in lower usage of TLB entries, resolving this issue.        |
