+# Лабораторная работа №4
+#### ПИбд-42. Минхасапов Руслан.

+#### Туториал

+- Второй

+- Третий

+
+#### Выполнение лабораторной работы
+
+Выбранная предметная область: Мониторинг серверов
+
+Сначала запустим продюсера и 1/2 консьюмера.
+
+Результат:
+![Скриншот 4](./pictures/lab_con1&2.png)
+
+Вывод:
+Так как скорость поступления сообщений в очередь первого консьюмера больше, чем скорость его обработки сообщений - очередь довольно быстро переполняется.
+Второй же консьюмер моментально обрабатывает входящие сообщения, из-за чего его очередь никогда не заполняется.
+
+Теперь запустим сначала один экземпляр первого консьюмера, а потом несколько, чтобы они разгрузили накопившуюся очередь.
+
+Результат:
+![Скриншот 5](./pictures/lab_con1&many.png)
+
+Вывод:
+Накопившаяся очередь постепенно разгружается благодаря нескольким одновременно запущенным экземплярам первого консьюмера.
