> We noticed that there was a significant drop in performance when entering
> page mode in the case of multiple subscribers.
> We created a topic and 100 queues bound to it. We ran our _GrinderRunner
> test_ in our inner test infra cluster with 500 threads producing message and
> 560 threads, each one picked a random queue to subscribe. The test showed
> performance is bad: 13000 msg/s sent and 5000 msg/s received.
