## What Speed up first-fit packing with a large lookback. ## Why Large plans fall back to a linear search through open bins. ## Implementation - Use the indexed path for large plans. - Bound the ring by the input size and allocate it lazily. - Preserve forward and reverse packing behavior. ## Benchmark Packing only, Apple M1 Pro, Go 1.26.3, median of 3 runs: - **16,384 files, lookback 8,193:** 74.10 ms → 0.71 ms (**104x faster**). - **24,000 files, lookback 10,000:** 139.46 ms → 1.89 ms (**74x faster**). `GOMAXPROCS=1 go test ./internal -run '^$' -bench '^BenchmarkSlicePackerLargeLookback$' -benchmem -benchtime=1x -count=3 -cpu=1` -- This is an automated message from the Apache Git Service.
