            Bug ID: 1148
           Summary: Performance on AESNI MB PMD does not scale properly
                    with number of threads
           Product: DPDK
           Version: 22.11
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: major
          Priority: Normal
         Component: cryptodev
          Assignee: dev at dpdk.org
          Reporter: pablo.de.lara.guarch at intel.com
  Target Milestone: ---

As number of threads is increased, performance per core on AESNI MB PMD
decreases (it should stay constant). The root cause of this issue is a global
variable in the IPSec Multi-buffer library. A patch has been generated to fix
it on the library, so users running the PMD with multiple threads are
encouraged to get the latest version (1.3.0) with the patch.
