Now, since the most stuff of libstdc++ is implemented it would be nice
to have a performance testsuite. For proffessional use the performance is
an important issue.


An aspect regarding my patch. Currently basic_string allocates only the
neccessary amount of storage, that strategy must lead to a low performance. 
It is a design problem. Perhaps there are other suspected places in the library...
