> a bench in jmh will be great. I measured it with `AdvanceSparseDISIBenchmark`: ```` Benchmark Mode Cnt Score Error Units AdvanceSparseDISIBenchmark.advance thrpt 15 669.502 ± 4.531 ops/ms AdvanceSparseDISIBenchmark.advanceBinarySearch thrpt 15 358.620 ± 1.102 ops/ms AdvanceSparseDISIBenchmark.advanceExact thrpt 15 752.444 ± 1.810 ops/ms AdvanceSparseDISIBenchmark.advanceExactBinarySearch thrpt 15 547.818 ± 2.278 ops/ms ```` Even I set target docs's inteval to 10, there is still a big performance degrade. Maybe I use too many `disi.slice.seek` in this binary search version. > you may find we are using VectorMask to speed up this, that was what i had in mind - get a MemorySegment slice if it is not null, and play it with VectorMask. I will try `VectorMask` when I get a chance. -- This is an automated message from the Apache Git Service.
