> With the updated compile flags, the performance of auto-vectorized code is slightly better than explicitly vectorized code (see results). Interesting thing to note is that both C-based implementations have `10X` better throughout compared to the Panama API based java implementation (unless I am not doing apples-to-apples comparison). This seems correct to me. The java Vector API is not performant for the integer case. Hotspot doesn't much understand ARM at all and definitely doesn't even have instructions such as `SDOT` in its vocabulary at all. -- This is an automated message from the Apache Git Service.
