## Разработка демонстрационных приложений
Предметная область: Доставка почты. Производитель - почтовая станция, которая сигнализирует о том, что пришла почта. Потребитель 1 - курьер тратит время и доставляет почту. Потребитель 2 - мы отправляет письмо по почте.
1. Publisher

## Результаты выполнения лабораторной работы
Вот работа наших 2 потребителей и производителя
![](pic/4.1.png)
Наш график, где нагляжно видно очереди и скорость прохода сообщений
![](pic/4.png)
Очередь с названием "courier..." - это наша очередь с курьером, а очередь "mail" - почтой
![](pic/4.2.png)
Вывод: Consumer2 - меньше нагружает память(из-за отсутствия простаивания очереди) и быстрее по времени, чем Consumer1(Реально, я вот щас пишу записку, а он до сих пор назначает курьеров😂)
