Hello,


More about message passing..

An advantage of shared memory model is that memory communication is faster as compared to the message passing model on the same machine.

Read the following to notice it:

"One problem that plagues microkernel implementations is relatively poor performance. The message-passing layer that connects
different operating system components introduces an extra layer of
machine instructions. The machine instruction overhead introduced
by the message-passing subsystem manifests itself as additional
execution time. In a monolithic system, if a kernel component needs
to talk to another component, it can make direct function calls
instead of going through a third party."


Thank you,
Amine Moulay Ramdane.
