> 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.
