    A commercial company already did that with a proprietary kernel module:

    What they won't tell you is that it's a proprietary module- shipping something with it to anyone other than in-house clients is a GPL violation against the Linux kernel itself.

      Well guess what? It ?sn't. At least not by much. The only reason for the massive speedup in D-Bus is because D-Bus is a userspace daemon that has to do A LOT of switching to Kernel Mode whenever it's used. Firefox needs to do nothing in kernel mode.

      Or to make a better analogy: Paying a bus driver to leave his bus and stand around outside the exact moment nobody needs to driven and have him haste back into the bus whenever customers are around makes no sense. Yet with D-Bus you advocate that.

      And once again: The kernel is modular - you don't want D-Bus don't build it.

        If you're using plasma fire, I'm thinking that Schlock just eats it.

        I'm thinking that we just take off and nuke it from orbit- it's the only way to be sure. >:-D

          Which proves my point?

            Everyone wants dbus. My desktop won't function without. But I have a PC, not a Nokia phone. Speed is not an issue.

              Speed is always an issue my friend. I you can do anything to improve it, do it.

                Like program everything in optimized assembler?

                  There are more messages between Firefox and X than D-Bus messages on my whole desktop. If it's just about eliminating the system calls and memory copies, moving either Firefox or X into the kernel would save way more CPU cycles than moving D-Bus.

                  Any other arguments why moving D-Bus into kernelspace is supposedly a good idea, while moving firefox isn't?

                    Maybe there needs to be a better more efficient way to do dbus message handling.

                      Nice strawman.
