Я создал продюсера, который использовал com.rabbitmq.client.connectionFactory
и отправлял 1 000 000 сообщений (40 байт) за 100 секунд.
Но теперь я хочу весеннюю абстракцию. Я не смог использовать com.rabbitmq.client.connectionFactory
, скорее, мне пришлось использовать org.springframework.amqp.rabbit.connection.SingleConnectionFactory
. При использовании этой фабрики соединений брокеру за 100 секунд отправляется только 100 000 сообщений (40 байт).
Есть ли у кого-нибудь опыт, почему производительность снижается так сильно (около 90%).
Код с использованием «import com.rabbitmq.client.ConnectionFactory;» это ->
