Sorry, Damjan. Maybe I confused you.
This is what I am talking about:
In esp_encrypt_node_fn(), the logic is like this:
u32 *recycle = 0;
…
vec_add1 (recycle, i_bi0);
…
free_buffers_and_exit:
if (recycle)
vlib_buffer_free (vm, recycle, vec_len (recycle));
vec_free (recycle);

We don't use recycle anymore (except at one place), mainly due ot the issue how
dpdk works.

Well, there is a vector named recycle to remember all old buffers, which
consequently means a lot of mem resize, mem_cpy when vector rate is 256 or so.
Counting all of these overhead, I’d say, I see around 7~10% impact, after
fixing openssl usage issue.
