If it's too slow (quantify and measure that), consider faster hardware first, it's usually cheaper than coder time over the long run.
That I disagree with on multiple levels. Sure, if you as a developer only write one program, which noone wants so it's running just on your box, you are right. It's cheaper to upgrade your hardware than spend time optimizing your program.

But if your program actually gets run on several thousand of different boxes, it become a different matter. Upgrading 2,000 boxes for $500 each means spending a million dollars. That's a few programmer years. And if you produce a program once a month, and each time you're investing in faster hardware, you'll run into limits (the bottom of your wallet, or the state of the industry) pretty fast as well.
