Maybe. The other possibilities are that (glGetDoublev GL_MODELVIEW_MATRIX bv) takes a long time or that the profiler is overcounting calls to foreign procedures for some reason. In any case, calling bytevector-copy instead of make-bytevector won't buy you much (if anything), and it may make your code harder to understand or to debug. There's no reason why bytevector-copy should run faster than make-bytevector; in fact, I'd expect make-bytevector to run faster than bytevector-copy.
