Shared object libraries are executable functions which are resident only in that library. Other programs are compiled with pointers to functions within the shared object and so, are much smaller than if they had been compiled with standard libraries. When compiling with a standard library, the entire function must be copied into the executable, not just a pointer. Not surprisingly, when a system is compiled using shared object libraries the executables are much smaller and the system disk space is used far more efficiently. The tradeoff of course is more disk accesses when starting an application.
