I don't mean to offend, but I think some of this would be obvious if you RTM. 

As to which is faster--depends on your CPU, the version of UNIX you're using,
etc.

There are a number of good references on the design, structure, and internals
of the UNIX operating system that describe this very well.  I'd recommend them
as supplemental reading--not light, but enlightening.

As far as IPC, I've found the docmentation, included with the operating
system (SVR5.3.X and SVR4.0) to adequate for me.
