I've been trying to use some of the noise functions included in Fragmentarium: Classic-Noise and Ashima-Noise.
These work very well, but are extremely slow.

Looking for alternatives I found a bunch of cool stuff:

Very simple and fast noise from IQ
https://www.shadertoy.com/view/4sfGzS
This is damn fast.

Here's a neat set of simplified, performance-oriented noise functions from Brian Sharpe:
https://github.com/BrianSharpe/Wombat
Perlin4D and Value4D noise functions are really performant.

And here's a full-blown library from the same author, although it's all in one file so you'll have to slice it into digestible bits depending on the needs.

Hope some it's useful.
