By the way, there are 0 figures for apache access / volume on
http://munin.debian.org/debian.org/klecker.debian.org.html

Given the high volume of static text content, we can think it (at
least) worth the try.
And you're right, that's currently not a issue, but a possible
improvement.
Apache will cache the compressed pages anyway, so the CPU impact would
not be that high, for an improved downloading time (serveral dozens of
%) on the user side where the pages will display faster.
And since the compression level can set, it can be used to tune the CPU
usage.
Best regards.
