Hello. I am reading Xen and the Art of Virtualization. I am curious as to why the async I/O ring buffers contain both requests and responses in the same ring. I have not seen this done before. Is it not more efficient to have one ring for each direction? What is the benefit of the single ring? ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.
