Android线程会自动暂停

Question

我正在尝试使用多线程进行一些计算。最多我将不得不进行100次不同的计算。即使我每次尝试平衡10个线程的开始，我都会在Log Cat上挂起线程消息。我认为这会扼杀性能。当我刚推出10个线程时，性能很好。

//launch thread for each accuracy values
        executor = Executors.newFixedThreadPool(100/accuracyInterval);

        int countThreads = 0;

        for(Integer acc: listAccuracies){

            Runnable worker = new MyRunnable(acc);

            if(accuracyInterval != 10) {

                if (countThreads == 10) {

                    while (threadsDoneCounter < 10) {

                        //Log.d("THREADS ","WAITING");

                    }

                    countThreads = 0;
                }

            }
            executor.execute(worker);

            countThreads ++;
        }


        executor.shutdown();

        // Wait until all threads are finish
        while (!executor.isTerminated()) {

        }

现在是MyRunnable的代码

public class MyRunnable implements Runnable {
        private final int accuracy;

        MyRunnable(int accuracy) {
            this.accuracy = accuracy;
        }

        @Override
        public void run() {

            Log.d("THREAD " , Integer.toString(accuracy) + " START");

            try {

                calculatePrediction(accuracy);


            } catch (Exception e) {


            }


            threadsDoneCounter++;

            Log.d("THREAD " , Integer.toString(accuracy) + " END");

        }
    }

当我必须启动100个线程时，可以做什么让它有更好的性能？我做错了什么？
