This may be a result of the way the libC you are using was compiled.
Try to compare performance tests that only depend on code you did write by your
own.
Most of the C++ standard library (at least the containers part I'm
using) is header only code, so it is mainly code I compile my self.
Not using libC is somewhat impractical in real world applications!
