+## Лабораторная работа №4 ПИбд-42 Артамонова Татьяна
+
+### Прохождение туториала
+1. ![tutorial-1.png](images/tutorial-1.png)
+2. ![tutorial-2.png](images/tutorial-2.png)
+3. ![tutorial-3.png](images/tutorial-3.png)
+
+### Запуск приложений и анализ скорости обработки
+
+1. Запуск Publisher, Consumer 1 и Consumer 2.
+* Consumer 1: Очередь order_queue_1 будет иметь некоторое количество сообщений, так как Consumer 1 обрабатывает сообщения с задержкой в 2 секунды.
+* Consumer 2: Очередь order_queue_2 будет практически пустой, так как Consumer 2 обрабатывает сообщения моментально.
+
+2. Запуск нескольких копий Consumer 1
+* Очередь order_queue_1 будет иметь меньше сообщений, так как 3 Consumer-а обрабатывают сообщения быстрее, чем 1 Consumer.
