I've never read that shared libraries are faster than static
executables.  One would think that, if anything, all of the hoops the OS
has to run through to map all of the symbols would cause applications
that use shared libraries to be slower to startup then statically built
executables.

As for system memory, a static executable will only use more system
memory if it's using code that other programs are also using at the same
time (libgtk, libxml, etc.).  In that case (and that case only) you
would have multiple programs loading the same symbols into memory and
thus would be wasting system memory.
