Hi Adrien, i tried the idea, this will got a ~10% speedup on JHM output, which is slightly less because it needs an extra loop to decode the delta. The benchmark using neighbor list = 32 (number of vints will be read), JMH output on java21: ``` Benchmark (baseline) Mode Cnt Score Error Units NeighborListsBenchMark.doSeek true thrpt 5 0.026 ± 0.002 ops/us NeighborListsBenchMark.doSeek false thrpt 5 0.029 ± 0.001 ops/us ``` The POC code is [here](https://github.com/easyice/lucene/commit/81954223abcf787e85ac6c4a1184e922db29a3cc) -- This is an automated message from the Apache Git Service.
