C# Multithreading (3) Advanced Threads

Aside from deadlocks, we only talk about performance issues. Although locks can always roughly meet the synchronization requirements, once there is competition, it means that some threads will be blocked. The more intense the competition, the more threads are blocked. Context switching The greater the number of times, the greater the scheduling cost, which will obviously damage performance in high-concurrency scenarios. Under the requirement of high concurrency, high performance and thread safety, the lock-free structure (non-blocking structure) makes its debut.
