Does anyone have experience reducing template code bloat using inheritance?

i hesitate rewriting our containers this way:

class vectorBase
{
  public:
    int size();
    void clear();
    int m_size;
    void *m_rawData;
    //....
};

template< typename T > 
class vector : public vectorBase
{
    void push_back( const T& );
    //...

};

I should keep maximum performance while reducing compile time

I'm also wondering why stl implementations do not uses this approach

Thanks for your feedbacks
