Again, I haven't seen your code or your data, but 50 minutes still seems
like a frightfully long time for such minimal processing on only 15 million
rows. If I were you, I'd keep optimizing (but then I'm pretty obsessive
about optimizing). Exactly how much time does GzipWriter take, for example?

Several people have correctly said that you stop optimizing when your
program is "fast enough" (which is a business decision, not a technical
one), but optimizing strictly inside of Ruby is a lot cheaper than
optimizing by dropping into C (which I do often enough), because you don't
incur the portability and other costs everyone has been talking about.
