so, when should you actually consider using a message queue?

hey everyone, im thinking about decoupling some services in our architecture. weve got a few synchronous communication patterns that are starting to cause some bottlenecks, and im wondering when you all typically reach for a message queue like RabbitMQ or Kafka. is it purely about performance, or are there other triggers like handling intermittent failures or enabling asynchronous workflows that push you in that direction? curious to hear your experiences and decision-making processes.
