Hi,
I am using dpdk-test-crypto-perf to measure the crypto performance of AES-NI MB
PMD.
The performance reports say "The SW PMD performance is linear scaling out with core
numbers",
but there are no result on multiple cores and this is not the case in my
environment.
What about your environment? Does anyone know how to improve it?
With DPDK v22.07/intel-ipsec-mb v1.20 and DPDK v22.11/intel-ipsec-mb v1.00 the
performance
did not scale out with the number of cores, but with DPDK
v17.05.2/intel-ipsec-mb v0.45
the performance do scaled out with the number of cores.
Results and environment are below.
