[jira] [Created] (CAMEL-19060) Scalability ceiling

Otavio Rodolfo Piske created CAMEL-19060:
--------------------------------------------

             Summary: Scalability ceiling
                 Key: CAMEL-19060
                 URL: https://issues.apache.org/jira/browse/CAMEL-19060
             Project: Camel
          Issue Type: Task
    Affects Versions: 4.0-M1, 3.18.5
            Reporter: Otavio Rodolfo Piske
            Assignee: Otavio Rodolfo Piske


When using the Seda producer/consumer on a large core count machine, it seems that Camel's throughput peak at around 9 producer / 9 consumer threads and after that starts to decrease [1]. This seems to indicate some kind of coherence issue - the cost to keep the threads coherent exceeds the system's ability to handle the load / use the system's free capacity.

 

1. This, of course, taking in consideration that the thread pool had been adjusted and the machine has enough capacity. Both of which were true.
