Not the case with arm gcc compiler(may be based outer function load).
The recent, external pool manager function pointer conversion
reduced around 700kpps/core in local cache mode(even though the
function pointers are not executed)

around 400kpps/core. On four core systems, around 2 mpps.(4 core with
10G*2 ports)

Practice is something we need to revisit based on the new use case/usage.
I think, the scheme of non external pcie based NW cards is new to DPDK.
