Summary
An S+ tree implementation in Rust achieves 40x throughput improvement over binary search by combining a B-tree-like layout (node size B=15), SIMD vectorization, batching, and cache-conscious prefetching. The design optimizes for high-throughput sorted search, using popcount-based branching and manual SIMD to minimize instructions per query. The code is open-source and targets applications like suffix array search in bioinformatics.
