   Hi @lucastetreault,
   Thanks for the tip, I noticed that I was missing a main test case.
   I did the following test again with the new MQ environment.
   
   - MQ version: Broker engine version 5.16.4
   - Broker instance type: mq.m5.large(vCPU:8 memory:8G) with EBS host on AWS MQ service.
   - Test case: Test 100ms delayed messages. This is the main issue in the previous version.
   - send message volume is 100,000 via 1 producer
   - message size is a string of consecutive numbers (ex: 000000~099999)
   - consumer: Use 4 consumers, I noticed that delay time is 100ms, which means that the consumer must get 10+ messages in 1 second.
   
   #### Test-1. 100ms with 4 consumer.
   
   The expected time for the message to be consumed
   
   >((100000*100)/1000) / 60 = 166.67mins
   166.67 / 60 = 2.7H
   
   Actual consumption time
   
   >StartTime: 2022-06-02 14:50:13.276
   EndTime:2022-06-02 17:37:39.99
   Total: 2H 48Mins => 168 mins
   
   
   #### Test-2. 100ms with 4 consumer.
   The expected time for the message to be consumed
   >((100000*100)/1000) / 60 = 166.67mins
   166.67 / 60 = 2.7H
   
   Actual consumption time
   >StartTime: 2022-06-03 04:04:45.827
   EndTime:2022-06-03 06:53:35.489
   Total: 2H 48Mins 49sec => 168 mins
   
   ### Summary
   From the above test results, I can be confirmed that the issue has been fixed and the process performance has been improved in the new version.
   
   Thanks for your help, let me notice the missed test case.
