IBM Power Ideas Portal
This portal is to open public enhancement requests against IBM Power Systems products, including IBM i. To view all of your ideas submitted to IBM, create and manage groups of Ideas, or create an idea explicitly set to be either visible by all (public) or visible only to you and IBM (private), use the IBM Unified Ideas Portal (https://ideas.ibm.com).
Shape the future of IBM!
We invite you to shape the future of IBM, including product roadmaps, by submitting ideas that matter to you the most. Here's how it works:
Search existing ideas
Start by searching and reviewing ideas and requests to enhance a product or service. Take a look at ideas others have posted, and add a comment, vote, or subscribe to updates on them if they matter to you. If you can't find what you are looking for,
Post your ideas
Post an idea.
Get feedback from the IBM team and other customers to refine your idea.
Follow the idea through the IBM Ideas process.

.There are no plans at this time to improve data queue performance, however I'd like to mention a few things about data queue functionality and the existing performance options.
Data queues are very robust, as they have a lot of ???extra" function available such as commands to create/delete, APIs to send and receive messages, save/restore capability to include the entries on the data queue, journaling and journal replay and remote data queues using DDM. But all of this added function, when enabled, does require additional pathlength. However, there are some attributes that you control that can affect the performance, such as the sequence option (ie. *FIFO, *LIFO or *KEYED), the ???Force" option which specifies whether the data is written to disk on a send or receive, the initial size, and the auto reclaim option. There is no single ???right" way to create a queue ??? it of course depends on how the application is using the queue. But if you have not examined these options before, it might be worth your time to better understand these options and make sure you have them optimized for your workload.
If you don't need all the extra function provided by data queues, you also have the option of using the more light-weight User queues. User queues have an API interface to create, but you must use MI instructions to enqueue and dequeue directly from the queue (there is no API wrapper). This makes them faster than data queues, although you still need to optimize the same queue attributes such as the queue type, size and number of messages and the reclaim storage options.
See the IBM i Knowledge Center for more information on using both data queues and user queues.
Due to processing by IBM, this request was reassigned to have the following updated attributes:

Interesting, what is their preference? Data Queues are way faster than other data objects such as say PF and LF. Can they support their claims?

An alternative to Data Queues for replacements to Arrays is to use User Indexes. These are capable of sorting data for you based on an index you provide.
