I'm assuming that is a QMFv2 message to the c++ broker, is that right?

You know you don't have to fetch the response for each message, right? 
You can send all 15,000 requests then process all 15,000 responses. Each 
response can be correlated to the specific request it refers to.

That would be my first suggestion. I'm not sure there would be an 
obvious benefit from merging these all into a single request. There is a 
little bit of overhead, but I wouldn't expect it to be the most 
significant factor. (I could of course be wrong!)

I'm using threads and others techniques in order to make it faster, but due to the amount
of request it's still slow.
