There was a little discussion about gcc's STL vs STLPort from the
perspective of performance, so I ported the test-suite at
http://askldjd.wordpress.com/2010/07/24/stl-performance-comparison-round-2-vc9-vc10-stlport/ from windows to Linux and compared my x86_64 gcc 4.5.1's STL to the in-tree STLPort 4.5, results are at

Native STL is typically better, except for large maps and some
edge-cases for std::string.

What does it all mean, probably very little, except to indicate that
there may be something worth investigating by someone who knows 
libstdc++ to see if there are some wins available in std::map's
