I once replaced a 10 machine Hadoop cluster job with a python script and parallel on my laptop because I didn't want to wait for hours for it to finish.

The i7 on my laptop with quite a few CPUS/threads and a few optimisations got the job finished in 10 minutes.

(I later put the Hadoop use on my resume, not the GNU parallel. That's the joke of modern job hunting. There is no interested in what you did, just buzzwords and leetcode. Luckily there are still a few places that value real work or I'd be too old to get a job. :) )
