Today one connection and one channel is opened per processed emails. Connections and channels are long lived objects, made to be reused. Flame graphs showed that this AMQP mailet represents ~1% of CPU occupation with just about 30 mail/sec. Note that 92% of this time is used opening/closing connections/channels. Moving connection and channel initialization at mailet initialization enables reuse and leads to dramatic enhancements of the performances of that very mailet. Note that retries are in place in case Rabbit is not up right at start - common with IE docker-compose. The testing strategy relying on mocks is brittle. Given that we have full-fledged integration tests in place, we can get rid of these annoying mock-based tests. ## Before   ## After  -- This is an automated message from the Apache Git Service.
