Michael Peter Christen 2fc8ecee36 ConcurrentLinkedQueue has a VERY long return time on the .size() method. See http://docs.oracle.com/javase/6/docs/api/java/util/concurrent/ConcurrentLinkedQueue.html and the following test programm: public class QueueLengthTimeTest { public static long countTest(Queue<Integer> q, int c) { long t = System.currentTimeMillis(); for (int i = 0; i < c; i++) { q.add(q.size()); } return System.currentTimeMillis() - t; } public static void main(String[] args) { int c = 1; for (int i = 0; i < 100; i++) { Runtime.getRuntime().gc(); long t1 = countTest(new ArrayBlockingQueue<Integer>(c), c); Runtime.getRuntime().gc(); long t2 = countTest(new LinkedBlockingQueue<Integer>(), c); Runtime.getRuntime().gc(); long t3 = countTest(new ConcurrentLinkedQueue<Integer>(), c); System.out.println("count = " + c + ": ArrayBlockingQueue = " + t1 + ", LinkedBlockingQueue = " + t2 + ", ConcurrentLinkedQueue = " + t3); c = c * 2; } } }		13 years ago
