URL: https://github.com/apache/lucene/pull/706


   SIMD-optimization for BKD `DocIdsWriter` was introduced in 
https://github.com/apache/lucene/pull/652 in order to speed up decoding of 
docIDs, but it leads to the regression in nightly benchmark.

   I tried to run `wiki10m` locally but can not reproduce the regression. I'll 
continue to dig, but i think we need to revert it first.
