I'm not sure what you mean. Could you outline how one of the 
testfiles.ck should look and how you propose I call chuck on it from my 
test script? Note that the "heavyness" on the cpu (in my case the number 
of instances of the .ck file) should be controllable from the bash 
script and hence not hardcoded into the chuck code.

Automation is on it's way, need some polish, but it basically works now!

Kernels are indeed interesting along with stuff like buffer size. 
However my main focus is to compare the various ugens (and stuff like 
modulo and casting), but once automation is working and the measurement 
is accurate it would be easy to test what-not.
