I’m working on a set of data refreshment scripts, which get data from file, do some transform, then send to a HTTP interface. Since the HTTP interface is kind of slow compare with reading and transforming data, I have several forked children processes to handle HTTP part.
Everything was done by Perl about 6 months ago, and everything seems good … until I started picking up Python. First sight is that Pyhon program is about 50% of Perl in term of LOC, which makes it easier to read, but seriously I don’t care about this too much as the logic is quite simple, however, when I tested Python programs and found that they are at least 50% faster than Perl’s, I felt nervous.
Two examples – Perl takes 13 seconds, Python takes 5, Perl takes 34 minutes, Python takes 10. Actually I’m really nervous at this moment thinking of my poor Python skills, I always worry if I made anything wrong with the translation (from Perl to Python), even I have verified result data for quite some times.
Will dig in after converting all scripts to Python.
