For dynamic libraries, yes. The overhead for loading a dynamic object
depends on the length of the loaded symbols, because it has to compare
the string length. Now consider that e.g. C++ mangles namespace(s), class
name(s), function name into one large symbol, it can be as large as 1000
characters and more.
