Robert Muir created LUCENE-9838:
-----------------------------------

             Summary: simd version of VectorUtil.dotProduct
                 Key: LUCENE-9838
                 URL: https://issues.apache.org/jira/browse/LUCENE-9838
             Project: Lucene - Core
          Issue Type: Improvement
            Reporter: Robert Muir


Followup to LUCENE-9837

Let's explore using JDK 16 vector API to speed this up more. It might be a hassle to try to MR-JAR/package up for users (adding commandline flags and stuff), but it gives good performance.
