Optimization adventures: making a parallel Rust workload 10x faster with (or without) Rayon
SMRTR summary
Profiling tools like strace and perf revealed bottlenecks in a Rust program using Rayon for parallelization. A custom thread pool implementation with CPU pinning and work stealing provided up to 50% speedup over Rayon for a specific workload. However, Rayon remains advantageous for its simplicity and wide applicability.
