> Note that it is terrible idea to benchmark small parts of your software individually and compose together the parts that are individually the fastest Certainly beats composing together the parts that are individually the slowest or not profiling at all. When you have to start worrying about shared CPU resources (main memory is a different matter), you are already doing much better than most software.
