> If we have a queue that has a huge amount of swapping going on (in and out), the ability to pull records from that queue is poor. When running a test, we had a producer continually pushing records into a queue with no backpressure. The consumer was very fast until swapping started to occur. At that point, the ability to consume dropped to only a few thousand events/second. Stopping the producer provided much better performance on the consuming side, which is problematic.
