Steps to reproduce the behavior in question

My application has to consume as many tasks as possible.
I am converting it in asynchronous mode using asynio and aio_pika.
But I found that it got idle sometimes.

advanced.config

What problem are you trying to solve?

Based on a very brief description (virtual no details) on what you are trying to accomplish or why, but also in general, 4.0.x is "the best version" because it is the only version that is maintained for everyone.

For "embarrassingly parallel" problems you'd likely benefit from using streams and/or superstreams, which are relatively recent and have matured by 4.x.
