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 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 (7):
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
