Considering there is a huge gain on the size of the HTML data to download when it's gzipped, I don't see why you shouldn't gzip it.

Maybe it uses a little bit of CPU... But not that much ; and it's really interesting for the client, who has less to download. And it's only a couple of lines in the webserver configuration to activate it.

(But let your webserver do that : there are modules like mod_deflate for the most used servers)

As a semi-sidenote : you are talking about compressing HTML content pages... But stop at HTML pages : you can compress JS and CSS too (they are text files, and, so, are generally compressed really well), and it doesn't cost much CPU either.

Considering the big JS/CSS Frameworks in use nowadays, the gain is probably even more consequent by compressing those than by compressing HTML pages.
