I figured that one out, but why is the performance so poor?

In other applications, I can push over half a million samples without causing issues.

Your OpenGL implementation may suck.

What sample rate are you using?

If it's quite a low rate, then with a large number of bins, there may be no way to achieve the given frame rate, given the sample rate, and FFT size.
