Now when you have descriptors in the stream loop, which can be factored out, the same can be moved out of the stream loop to \"up above\", which has exactly the same effect.. You can think of something like 2a + 2b = 2(a +b) The advantage of which you have a smaller CA PMT object. The shorter the communication, the less error prone it is. Additionally lesser time taken for the CA PMT object to be transferred.
