In my develop computure, when execute 1 billion times encode_varint64. `v | B` version averagely uses 95095 in 5 times. `(v & (B - 1))` version averagely uses 96103 in 5 times. It can improve aboat 0.5% ～ 1%. Encode_varint64 use high frequency in many case like bitmap_value, page_pointer encode and so on. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
