[Haskell-cafe] OpenGL performance issue on OSX

I'm using OpenGLRaw and I'm getting 3 frames per second trying to draw 8000 triangles. When I profile the application, I see that almost all of the time is taken by a call to CGLFlushDrawable, which is apparently OSX's function for swapping the back buffer to the front buffer. Has anyone else run into a problem like this? I seem to recall a thread a while ago about a Haskell specific OpenGL performance issue, but I can't find it now.
