Benchmarks for TSX (Hardware Transactional Memory) vs STM (Software Transactional Memory) vs lock-free vs Naive lock (std::mutex/spinlock) Implementations: ---------------- 1. Queue 2. Stack 3. Counter Note: the TSX implementation based on the tbb::speculative_spin_mutex. The mutex fallback to spin lock in case of no TSX support.
