Depends.  If you look at the assembly output, a "direct" call actually 
jumps
to a stub of 8 insns and executes those before getting to the real 
target.
However, the linker eliminates stubs in all cases where that's 
possible, so
if the caller and callee are both present at static link time, the 
direct
call winds up really being direct, therefore faster than going through a
pointer.  Calls to shared libraries do execute the stub code,
and in that case going through a pointer is faster.
