Performance analysis of the low -delayed primitive concurrent queue in the java class library

Performance analysis of the low -delayed primitive concurrent queue in the java class library introduction: The concurrent queue is a commonly used data structure in multi -threaded programming, which is used to achieve data sharing and exchange efficiently in multi -threaded environments.Low latency is one of the important requirements for concurrent queue performance in modern computer systems.The Java class library provides a variety of classes that achieve low delayed original concurrent queues. This article will perform performance analysis and comparison of these classes. background: In concurrent programming, multiple threads are often required to share and exchange data.In order to ensure the consistency of the data and the correctness of concurrency access, the special data structure needs to be used to achieve synchronization and mutual exclusion between multiple threads.The concurrent queue is a data structure suitable for the multi -threaded environment, which can realize the data exchange and sharing of thread security.Low latency is one of the important requirements of concurrent queue performance in modern computer systems, because high latency can cause thread blocking and affect the response time and concurrency processing capacity of the system. Low delayed original concurrent queue in the Java class library: The Java class library provides a variety of classes that achieve low delayed original concurrent queues, including: ConcurrentlinkedQueue, LinkedTransferqueue, and SynchronousQueue. 1. ConcurrentLinkedQueue： ConcurrentlinkedQueue is a non -blocking, unbounded thread security queue.It uses CAS (Compaare and Swap) operation to implement atomic operations that are accessed in concurrent access.In the scene of concurrency, the ConcurrentlinkedQueue can provide better performance and low delay. Example code: ConcurrentLinkedQueue<String> queue = new ConcurrentLinkedQueue<>(); // Add element to the queue queue.offer("Element 1"); queue.offer("Element 2"); queue.offer("Element 3"); // Get elements from the queue String element = queue.poll(); 2. LinkedTransferQueue： LinkedTransferQueue is a blocking, unbounded thread security queue.It uses a lock -free algorithm to achieve efficient concurrent operations.In the scene of concurrency, LinkedTransferqueue can provide lower latency and high throughput. Example code: LinkedTransferQueue<String> queue = new LinkedTransferQueue<>(); // Add element to the queue queue.put("Element 1"); queue.put("Element 2"); queue.put("Element 3"); // Get elements from the queue String element = queue.take(); 3. SynchronousQueue： Synchronousqueue is a blocking queue without a buffer.It supports zero -volume element exchange, that is, the insertion operation must wait for another thread to take out operations in order to continue the execution.In the scene of concurrency, Synchronousqueue can provide lower latency and high throughput. Example code: SynchronousQueue<String> queue = new SynchronousQueue<>(); // Add element to the queue queue.put("Element 1"); // Get elements from the queue String element = queue.take(); Performance analysis: For low latency requirements, ConcurrenTlinkedQueue is a better choice.Its non -blocking characteristics make threads not blocked and can achieve lower latency and high concurrency capabilities.LinkedTransferQueue and SynchronousQueue may provide better performance in real concurrent scenes, but for simple concurrent demand, ConcurrentLinkedQueue is a lightweight and easy -to -use option. in conclusion: The Java class library provides a variety of classes that achieve low delayed primitive concurrent queues.When choosing a suitable queue class, it is necessary to analyze and compare specific scenes and performance needs.For simple concurrency requirements, the ConcurrentlinkedQueue may be a better choice; for a higher throughput and lower latency scenarios, you can consider using LinkedTransferqueue or Synchronousqueue.
