gzip and how to use it

seems a few sites i have read have differing options on how this is used. this is just a general "how do i make use of it" type question.

this is a very "for dummies" kind of question, so any pointers a开发者_JS百科re greatly appreciated.

the source of this information was using YSlow to analyze site load time.

mod_default is a burden on the server's cpu. Save your generated content into gzipped files and then serve them with mod_rewrite. I do so on my home page.

There was a great tutorial on how to do that, but it seems it has been deleted. Google cache still has it, though.
