Hi,
On my test setup, which is server machine with Intel(R) Xeon(R) CPU
E5-2680 v3 @ 2.50GHz and 16GB RAM. I am comparing dpdk aesni_mb
l2fwd-crypto decryption results with VPP dpdk-esp-decrypt node. I see 1
Mpps difference. l2wd-crypto can process 3 Mpps(size 168) but vpp dpdk
crypto can only process around 2 Mpps.
Right but there is no comparison in terms of L2 feature support, the
DPDK code is sample code only, VPP is a full l2 stack.
There is 1 Mpps difference. May be due to the fact that dpdk-input and
crypto-input are process on the same core?
Well VPP does a double pass to route the encrypted packet, that the DPDK
IPSEC sample code does not do, but again I would argue that is behaviour
you want.
Is it possible to run dpdk-esp-decrypt node on another core just for
encryption decryption. This way we can avoid re-ordering of the packets
and at the same time use multicore for single ipsec flow.
Each core run's an entire copy of the VPP stack, you can't break a
pipeline up over multiple core's easily AFAIK.
