Are you talking about web/internet accelarators? If so, see below;

1. Accelerators stores copies of frequently looked at pages to make them quickly accessible.
2. Accelerators only download the updates if a web page has changed slightly since you last viewed it.
3. Accelerators prefetch certain pages onto your computer in advance.
4. Accelerators managing your Internet connection to reduce delays.
5. Accelerators compress data before sending it to your computer.

If you're talking about tweaking programs, what these usually do is expand the allowed size on your TCP window size.
