8 cores just mean it takes longer before you hits this bottleneck, so thats a non-argument. For low-traffic sites, such as a blog, its of course fine =)

Freddy, when you say memory management is ‘where you have to worry’, what do you mean specifically? Do you just mean running out of memory (and having to swap) or something else like being limited by internal RAMCPU bandwidth?

Plus you do still have to worry a lot about CPU these days if you’re doing anything reasonably complex/dynamic.

Just remember that the mod_deflate rules are virtualhost specific! They are NOT system wide.

Evert is also somewhat correct BUT with todays 8core cpus memory management is where you have to worry the most not cpu on a apache server.

Even though on-the-fly compression will help you in the short term, you’ll soon hit CPU limits if your site will start to grow.

We stricly use gzip for pages which can be cached for a couple of minutes, pre-generate the pages pre-compressing them. So those pages will only be compressed every 5 minutes or so instead of for every request.
