+## Данные из RabbitMQ Management UI:
+
+#### 1. Показания очереди queue_1 при одном запущенном экземпляре Consumer_1
+![изображение 1](./images/q_1_one_comsumer_1.jpg)
+#### 2. Показания очереди queue_2
+![изображение 2](./images/q_2.jpg)
+#### 3. Показания очереди queue_1 при двух запущенных экземплярах Consumer_1
+![изображение 3](./images/q_1_two_comsumer_1.jpg)
+#### 4. Показания очереди queue_1 при трех запущенных экземплярах Consumer_1
+![изображение 4](./images/q_1_three_comsumer_1.jpg)
+
+### Вывод:
+Из скриншотов видно, что из-за моментальной обработки сообщений в Consumer_2, очередь queue_2 никогда не заполняется.
+Consumer_1 же тратить на обработку 2-3 секунды, из-за чего очередь queue_1 существенно заполняется при одном 
+запущенном экземпляре.
+Если уже запущенных экземпляров Consumer_1 будет больше, чем один, то очередь будет заполняться не так быстро,
+и в определенный момент не будет заполняться вообще, что будет при оптимальном количестве запущенных экземпляров Consumer_1.
