> @9prady9 In the benchmark results above, why the performance drop occurs for the first pair of `BenchmarkBitmapAndWithPopCount` runs (from 18 to 13 G/s) but not for the other runs? Aligned bitmap ops(the first two runs in both sets: with and without pop count) does have performance drop irrespective of whether we compute the validity count inside `AlignedBitmapOp` function or outside it by calling `CountSetBits`. When done inside the `AlignedBitmapOp` function, the drop is significantly higher. -- This is an automated message from the Apache Git Service.
