[GitHub] [james-project] chibenwa edited a comment on pull request #508: JAMES-3604 Improve RabbitMQ resiliency

   CPU utilisation related to RabbitMQ as expected increased (1.30 % -> 2.6%) however latencies went from 67ms to 90+ ms at ~800 req/s.
   
   RPC related to `Channel::confirmSelect` done repeatedly are rather expensive, and I notice some active creation of channels.
   
   As such, I feel unconfident with the publish / confirm part of the work and would split it to another pull request...
