Maybe we can add it at the same wiki page? Also, would be nice assign each test to someone that wants to perform it. As an example, I have my lab where I can make benchmarks in parallel with your lab, if we assign tasks we won't have duplicated tests(in case we don't want it). I will update soon the information about my LAB.

I think these are all fine ideas. Running the same tests in more than one environment is good. If our = results can be reproduced, it means our methods and conclusions are valid. =E2=80=94=20 Dan Langille http://langille.org/
