Streamlining AJP with UNIX domain sockets?

[Gunther Schadow <gu...@aurora.rg.iupui.edu>]

Hi,

quick question: AJP is used mainly in localhost type connections in order
to avoid any security issues.  If so, and if we focus on Unix systems for
now, wouldn't a UNIX domain socket be faster than a loopback IP connection?
I know UNIX sockets are not supported with 100% pure Java, but may be
one could add a JNI module for domain sockets and register UNIX domain
sockets as a URL scheme so that one could write programs that do not
heavily depend on UNIX yet can use that resource if available.  Any ideas?
Does it matter?

regards

It does matter, but I don't think it's a very high priority ( it doesn't 
scale up with load balancing, so the focus should still be TCP  ).

It will probably be much faster than TCP, so it will be a great
contribution if someone has extra time.

IMHO, the speed gain is not worth the time it takes to support such a
solution.

there are plenty of other places to find performance improvements within the
code that do not require platform specific solutions.
