Object Loader for C++

I've made a few small games in C++ and OpenGL, but I've noticed that the .obj loader I use to import 3D models is really inefficient.  My search for a better 3D object loader, for any file format, isn't going well.  Could any kind Anon here recommend me a starting point to find a cleaner, faster (and preferably free) object loader?

SICP should... prepare a piece of merchandise for use by stirring or kneading?
SICP should... cause a praiseworthy character to toil or labor?
SICP should... set the advancement of prosperity into motion?

Sorry, if you think any of the above make sense, you clearly need English lessons.
