We already use SSE2/Neon here, and and a good compiler can unroll 2 vectors to work on 32-bytes per loop iteration. Profiles of COPY FROM should not show ASCII validation to be a large part of the profile anymore. The bottlenecks are most likely elsewhere. I don't believe this is worth it. -- John Naylor Amazon Web Services
