Alan, I also meant to say that I didn't understand the comment about "in production it seems that DomainSocket is less commonly used". The current implementation of short-circuit read definitely utilizes DomainSocket, and it's very common to enable this in production clusters. The documentation page you mentioned includes discussion of a legacy short-circuit read implementation, which did not utilize UNIX domain sockets, but the legacy implementation is rarely used in practice now.
Oh, OK - thanks for the clarification. I couldn't find much about DomainSocket other than the link I posted and that didn't make it sound like it was used all that much. I'll make sure the JIRA reflects what you said above.
Interestingly, INET sockets are faster than UNIX sockets on Linux as well as on Solaris. There's not much in it, around 10% in both cases, and I suspect socket throughput isn't the rate-limiting step anyway.
