hi~ dear,
I need to find the fastest IPC mechanism between processes or threads.
I believe that It is different case by case.
in my case, there are two case.

1st, transfer small data. ex)  some arguments, IDs
2nd, transfer big data ex) raw audio, image, video data

Please correct any misunderstandings that I have,

Also, any additional clarification would be greatly appreciated.

When in 1986 Apple bought a Cray X-MP and announced that they would use it
to design the next Apple Macintosh, Seymour Cray replied, "This is very
interesting because I am using an Apple Macintosh to design the Cray-2
supercomputer."

The fastest IPC will be between threads -- no IPC is required at all.

That is specific to Solaris.
What made you believe OP is interested in a Solaris-only solution?

Linux has at least some support for doors (or at least, there is/was a
Linux doors project).

What makes you believe the OP isn't interested in a Solaris-only
solution?

Shared memory is the fastest.  When you've got several processors or a
multi-core processors,  in the best circumstances you'll need only one
microprocessor cycle to communicate between the threads or processes.
Any other scheme will be slower.

There is an implementation (someone's research project?).
The sourceforge project lists it as doors-0.1 and has never been
updated since 2001. I'd say this project is pretty dead.

The implementation is by no means "available on Linux" (as in
"you can walk up to a random Linux machine and it will have doors
available").

Most people who post here aren't.

The ones that are (if they have some common sense) either say so,
or (cross)post to comp.unix.solaris.

On the other hand, the OP did say they wanted the fastest IPC mechanism.
If doors are it, and if a fast IPC mechanism is a very high priority,
maybe they're willing to adopt Solaris purely because it has doors.  :-)
