Hello,

I currently manage a RabbitMQ cluster (3.10.0) with nearly 400 queues and approximately 7 million messages per day.

I plan to upgrade the cluster to the latest version and would like to know the optimal configuration.

My cluster currently uses 3 VPSs with 16 GB of RAM, 6 dedicated cores, and 320 GB of SSD storage (running on ubuntu)

My question is: do I really need that much RAM and so many CPU cores?
Is 8 GB of RAM with 4 dedicated cores sufficient?
Thanks for your feedback
