# “Ruby faster than Python and Perl!” ORLY? Ruby faster than Python and Perl! cries the headline. This is based on a benchmark that tests i = i + 1 in a loop, so it’s a particularly useless benchmark, even in a world of benchmarks designed to test unrealistic scenarios that make the benchmark author’s product look good. But wait! A commenter accuses the poster of cheating! (On a benchmark? No!) >Ummm…. Why did you test Ruby with less data than you tested Python and Perl? You cheated. As it

Toggle navigation Eli Bendersky's website Python - paralellizing CPU-bound tasks with concurrent.futures January 16, 2013 at 05:50 Tags Python , Concurrency A year ago, I wrote a series of posts about using the Python multiprocessing module. One of the posts contrasted compute-intensive task parallelization using threads vs. processes. Today I want to revisit that topic, this time employing the concurrent.futures module which is part of the standard library since Python 3.2 First of all, what are "futures
