<br>
If so, are you relying on the fact that the prefetch limit applies *across* queues rather than *per* queue?<br>
<br>
That feature entails considerable implementation complexity and has a substantial performance impact on consuming from basic.qos-limited channels in general. And I've just found a bug in that area of the code, fixing of which will make the implementation even more complex and hurt performance even more.<br>
<br>
Hence I am trying to gauge people's opinion on whether we could make the prefetch limit apply per-queue instead.<br>
