+ Alternatively, x86_64 applications can use the non-blocking ring or stack mempool handlers. When considering one of them, note that:
- it is limited to the x86_64 platform, because it uses an instruction (16-byte compare-and-swap) that is not available on other platforms.
- it has worse average-case performance than the non-preemptive rte_ring, but software caching (e.g. the mempool cache) can mitigate this by reducing the number of handler operations.
