Dawid Weiss commented on MAHOUT-1204:
-------------------------------------

Caliper is awesome but I don't know if it's the right choice for benchmarking 
larger pieces of logic (don't know what you want to apply it to). Where it 
really shines is at microbenchmarking (or in general for short execution 
times). The scaling factor ('reps') may be a problem for larger pieces of logic 
where the number of repetitions cannot scale with the demands of the background 
probing heuristic implemented in Caliper. At least that's my impression (and I 
have been using Caliper for a longer while now).

For smaller snippets of code it's an awesome tool though (especially for 
benchmarking cross-JVM performance of the same code).
