I replaced a python/mysql daily process that takes 25 minutes to run with a perl/redis process that takes 1 minute to run, so it runs multiple times a day. Mgmt asks me to convert it to python/mysql, "...but keep the run time at one minute. That's great!"

No.

If works faster not need to reimplement imho.

Sure. The app I replaced was very poorly written, and supported by a bad programmer. The approach it takes is bad, and a ground-up rebuild was the only solution I saw as workable.

That said, nothing outruns perl in text processing, except compiled code, and no backend operates faster than redis.
