Because I like sitting around optimizing Clojure code I looked into this

When numbers fluctuate like that I'm pretty sure you're hitt

If you change the size of your CA, is the ( java time / clojure time ratio )
roughly constant ?

Here is a version that is approx 10 times faster: http://snipt.org/Olml
The code structure is basically the same but it uses integer arrays
for storage, some manual inlining and lo
I can't see your code due to the IT policies here, but I can make some
generalizations - these are assuming your code is correct and you're
not accidentally using an exponential algorithm (which I wouldn't
preclude, 4 minutes does sound truly excessively slow, even for
vectors).
Vectors are signif

Hi again,
I have tried a few more things:
I have done the same in Java but using an array
of Integers, instead of an array of ints. It just takes
78 ms. (more than 16, still far less than 4 secs).
I have also tried with an update function which just returns a
fixed 1. It still takes some
