Schedule Message Delivery Producer Performance

[MattFaulkner <ma...@gmail.com>]

Hi,

I'm looking at using the scheduler for delaying a large number of messages.
However, when testing I notice there is a big performance difference between
having the AMQ_SCHEDULED_DELAY value and not.

I created a simple producer and sent 1 million messages. 

WITH delay time taken - 2429 seconds
WITHOUT delay time taken - 264 seconds

Is this expected behaviour or am I missing something here?

Version: 5.13.2

Thanks,

Not really sure what the measurement is based on given the lack of 
details but I am not surprised that the scheduled message sends take 
longer, the scheduler store is not a high performance message store and 
I would not treat it as such.  If you are blasting a million messages at 
the broker with scheduled delay values then I'd maybe suggest that you 
take a step back and reconsider some of the design choices that got you 
there.
