ARTEMIS-2399 Improve performance when there are a lot of subscribers
URL: https://github.com/apache/activemq-artemis/pull/2750#issuecomment-511587691
 
 
   @wy96f any chance for higher resolution images? (and whilst at it english 
titles to help understand the graphs). 
   
   
   Re impl detail, 
   
   As i mentioned in the email lists, i think what ever change is made, as this 
is soo core to foundation of the broker, it will be a big and risky change perf 
wise,  it is key (a must for me) this is something we let people toggle on, and 
we leave the default behaviour as was so user dont get suprises and also 
de-risks, at least for a few releases, this way if there is a perf issue or 
usecase not covered, there wont be any impact to other users.

> 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.
