| Doc Text | Cause: The RETBleed vulnerability mitigation in RHEL 9.2 causes a performance regression with OVS-DPDK running on Intel E810 interfaces. Consequence: Around 20% drop of performance. Workaround (if any): Add `retbleed=off` in kernel boot arguments. Result: Performance should be on par with previous releases. |

Result: Performance should be on par with previous releases. | There is currently a known issue where the Retbleed vulnerability mitigation in RHEL 9.2 causes a performance drop of approximately 20% for Open vSwitch with Data Plane Development Kit (OVS-DPDK) on Skylake CPUs. Workaround: Add the `retbleed=off` option to kernel boot arguments to return performance to a similar level to previous releases. |

This performance regression will only happen if C-states are disabled in the BIOS, hyper-threading is enabled and OVS-DPDK is using only one hyper-thread of a given core. Workaround: assign both hyper-threads of a core to OVS-DPDK and/or to SRIOV guests that have DPDK running. |
