Carsten also has some examples.

That would be very helpful. I would love to see that code.

I have a service program that wraps functions for the user queue object

Actually writing to User Queues is a lot simpler in RPG than in C. They are
tough in C although there are a lot of examples out there using them in C.
Let me know if you are interested.

According to IBM documentation, a USRQ will have better performance than a
DTAQ. I have an application that is experiencing performance issues on
some customer systems and we now think that this is tied to a lot of data
going through a data queue. Unfortunately, IBM documentation on how to
work with user queues is nearly nonexistent. The only think I can find is
an example written in C which is of little use to us. I see where you have
to use MI to read and write to a user queue and that doesn't scare us all
that much, but it would be good to know that diving into this project was
going to produce tangible results.
Does anyone have any experience with user queues and have you done it in a
language other than C? We need to be able to write to one and, in a
separate process, read from it all in FIFO sequence.
