However, parsing is something Perl is very good in. Thus you can simply obtain, a Perlish solution is the quickest way, so you also don't need to know how quick Perl is. Sorting is something different as there might be very quick c solution specialised to sorting on hard disks. But that depends also on the size of the files. I assume simply 30_000 lines of 100 columns each => 3_000_000 bytes = 3 MB. 3 MB would be nowadays so less that it Perl's memory wasting wouldn't create problems. Unless memory problems, common sort routines are very quick in all languages, also to Perl. > * Parse File by File, and save the parssed file in a DB (MySql) Depends on the time of the database. > * Check to see if I need a backup of the Zip File Depends on the check routine, but I assume it is also language independent. > * Finish > > How good its to do this in 10 seconds? It's always possible, you'll only need a computer that is expensive enough. However, if my guess of 3 MB is right, it should be easy with nowadays desktop pcs in every language. > Exists a website with benckmark running times in Perl? http://www.google.com/search?q=benchmark+perl+programming+languages Greetings, Janek -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
