+ * The memory copy performance differs on different AArch64 micro-architectures.
+ * And the most recent glibc (e.g. 2.23 or later) can provide a better memcpy()
+ * performance compared to old glibc versions. It's always suggested to use a
+ * more recent glibc if possible, from which the entire system can get benefit.
+ *
+ * This implementation improves memory copy on some aarch64 micro-architectures,
+ * when an old glibc (e.g. 2.19, 2.17...) is being used. It is disabled by
+ * default and needs "RTE_ARCH_ARM64_MEMCPY" defined to activate. It's not
+ * always providing better performance than memcpy() so users need to run unit
+ * test "memcpy_perf_autotest" and customize parameters in customization section
+ * below for best performance.
+ *
+ * Compiler version will also impact the rte_memcpy() performance. It's observed
+ * on some platforms and with the same code, GCC 7.2.0 compiled binaries can
+ * provide better performance than GCC 4.8.5 compiled binaries.
