FYI: If you are comfortable and like to experiment, you could try flashing a custom ROM.

HOWEVER, please don't feel like you NEED to do this to have a fast phone. I found (Sprint) stock to be plenty fast. I don't find the custom ROM I'm running (MightyRom) to be faster than stock (others might, but I'd want to see repeatable benchmarks to prove that). That said, a custom ROM will make your phone more functional and prettier without a loss in speed. Bottom line, stock should be working way better than you describe.
