> We can replace it with Bit21With2StepsEncoder in future when the performance is comparable to x86. I wonder what mechanism we could use to remind ourselves when performance of `aarch64` catches up? It's frustrating that such arch-specific low level details find their way up to javaland clouds / Lucene level, but it seems a necessary evil for now. Maybe Lucene someday needs a little quick baby microbenchy that runs once on JVM startup (somehow) and identifies which of the N SIMD / scalar options we have for decoding blocks of different BPV ints are best for the current "context" and then remembers and uses the fastest options during decode of BKD/postings/doc values/vector-dot-products/whatnot. -- This is an automated message from the Apache Git Service.
