Hello, everybody
I find that many codes in DPDK only prefetch the first cache line of struct rte_mbuf.
The struct rte_mbuf has 2 cache lines.
Why not prefetch the second line ?
Is it hinted that the CPU (x64 or ARM) always automatically prefetch the next immediately followed cache line ?
Thanks a lot !
