Copied from chatterbox: saskaqueer's mind boggles over the newest SoPW. Imagine a "magical module out there" that could "save a bunch of files with only one I/O call". That'd be amazing to see ;)

That aside, I'd say 20 seconds isn't too bad for creating and manipulating 417 files. If your code can use any adjustments for speed, it would most likely be with the code you are using to split up a chunk of data into 12 records per file. If the bottleneck here is indeed the file I/O for outputting the new files, then that's about the best you're going to get.

How are you reading in this 5000+ record file? Are you reading it in all at once into memory, or are you looping through it 12 records at a time to split it up? If you're pulling everything into memory at once, that might be your problem there.
