I actually haven't given the full story, here.  The "perlin" noise 
c-extension was actually using simplex noise, which is faster than 
perlin noise.  So the extension had two advantages over the gem I 
listed:
a)  Simplex noise (faster than perlin)
b)  Coded in c

So it may be a bit hard to compare them.

I didn't actually create benchmarks, unfortunately.  There was a task I 
was performing within the program that ran noticeably slower.
