+
+### Вывод:
+Из-за моментальной обработки сообщений в Consumer2, его очередь никогда не заполняется.
+Consumer1 же тратит на обработку 2 секунды, из-за чего соответствующая очередь существенно заполняется при одном 
+запущенном экземпляре.
+При нескольких запущенных экземплярах Consumer1 очередь заполняется существенно медленнее, и перестаёт заполняться совсем при определенном кол-ве запущенных экземпляров.
