My test case is: Send a huge amount of messages into the broker. Let several hundred thousand accumulate. Then start consumers and see how long it takes to drain the queues and topics. The result is: For queues- excellent. Performance is amazing. A few 1000ms Journal append messages, but recovery performance exceeds my requirements. For topics- Index updates in the 2-700ms range. This happens every second or so and locks the consumer, so recovery is extremely slow. This is very similar behaviour to what I saw with Topics and Queues before Rob applied the fix for cursors in KahaDB. Is it possible that the fix needs to be also applied to topics?
