@imay From the point of view of implementation, our implementation should be copied from leveldb, but leveldb has removed some unnecessary bit operation in this pr https://github.com/google/leveldb/commit/cf1b5f473259e46c667f3fb5a28bcd884ee3a102#diff-0f30ecb01c7888631c52ec595204f7f0 , so I think we can also change to the same implementation as level db, although this change improves performance not particularly big
