> Subject: [PATCH v4 0/8] Crypto-perf app improvements
> 
> This patchset includes some improvements in the Crypto performance
> application, including app fixes and new parameter additions.
> 
> The last patch, in particular, introduces performance improvements.
> Currently, crypto operations are allocated in a mempool and mbufs in a
> different one. Then mbufs are extracted to an array, which is looped
> through for all the crypto operations, impacting greatly the performance, as
> much more memory is used.
> 
> Since crypto operations and mbufs are mapped 1:1, the can share the same
> mempool object (similar to having the mbuf in the private data of the
> crypto operation).
> This improves performance, as it is only required to handle a single
> mempool and the mbufs are obtained from the cache of the mempoool,
> and not from an static array.
> 
> Changes in v4:
> - Refactored test code, to minimize duplications
> - Removed --qp-nb parameter. Now the number of queue pairs
>   per device are calculated from the number of logical cores
>   available and the number of crypto devices
> 
> Changes in v3:
> - Renamed "number of queue pairs" option from "--qps" to "--qp-nb",
>   for more consistency
> 
> Changes in v2:
> 
> - Added support for multiple queue pairs
> - Mempool for crypto operations and mbufs is now created
>   using rte_mempool_create_empty(), rte_mempool_set_ops_byname(),
>   rte_mempool_populate_default() and rte_mempool_obj_iter(),
>   so mempool handler is set, as per Akhil's request.
> 
> Pablo de Lara (8):
>   app/crypto-perf: refactor common test code
>   app/crypto-perf: set AAD after the crypto operation
>   app/crypto-perf: parse AEAD data from vectors
>   app/crypto-perf: parse segment size
>   app/crypto-perf: overwrite mbuf when verifying
>   app/crypto-perf: do not populate the mbufs at init
>   app/crypto-perf: support multiple queue pairs
>   app/crypto-perf: use single mempool
