Addressed in df459692. I added a deterministic Criterion benchmark that reports encoded bytes plus encode/decode timings. In one 20-sample local run over 16,384 INT32 values, moving from 128/4 to 256/4 reduced stable-width output from 66,699 to 66,123 bytes, encode time from 66.76 to 62.71 us, and decode time from 9.71 to 9.16 us. For locally varying widths, output grew from 35,131 to 42,161 bytes while decode time fell from 10.59 to 9.22 us. The public docs and PR body now use these results to recommend retaining defaults unless representative data shows a worthwhile compression/throughput trade-off. -- This is an automated message from the Apache Git Service.
