resources needed by different apache2_mpms

[cjubon]

On my desktop machine, I've installed apache. I'm not interested in performance, since it's a testing server for web-development and doesn't connect to outside my LAN (hopefully ).

I have two install options:

• APACHE2_MPMS="prefork" and USE="-threads" (which needs an extra entry in /etc/portage/package.use because threads is enabled globylly in /etc/make.conf), or
• APACHE2_MPMS="worker" USE="threads" where using threads would be my default configuration.

Now I just wondered which setup uses less resources (I mean CPU and RAM). It's not that important, but it would be interesting.
Thanks for your answers.

Prefork mpm uses one process for every request. It's the most tested and stable mpm. But it's memory hungry.

Worker mpm aims at reducing memory usage. It uses a mixed process/thread architecture. As a drawback, requests are not isolated anymore. If one process dies, all its threads die, affecting many requests.

As for the CPU usage, I would bet it's similar.

Thanks for the answer, manaka. I seems I'll stick with prefork.
