Is GLUT hindering performance?

Hello!

I was wondering whether using GLUT hinders the performance of the
application in comparison with the plain platform-dependent approach
of creating a window using the OS API.

What prompted me to write this mail is that I have this fairly simple
program (does some calculations but nothing significant) that takes
100% CPU. It's quite possible that this maybe due to a bad driver,
since I recently updated to an unstable version of my Linux
distribution.

But, anyway, do you have any observation on this issue, does GLUT make
the game program slower or the difference (if any) is negligible?

Thanks,
Petar.
