This is because most applications have natural application overhead, and also because many programmers lack a thorough understanding of the details and eccentricities of GL. If you are writing a simple display-only, immediate-mode GL program, then it will run faster using straight GL, but not much. However, if your program has scene traversal, interactivity, picking, bounding box calculations, and other object space tasks, then Inventor will perform better for you. This is because Inventor is specially tuned to make optimal use of GL on each SGI machine. Furthermore, Inventor supports render caching which results in peak GL performance in most cases. We have found that in many cases, Inventor programs run FASTER than the original GL program, and that the programmer productivity increases easily outweigh the overhead of the toolkit.
