Subject Re: [users@httpd] Apache 2.4 optimisation for a virtual server with low resources.
Date Tue, 12 Aug 2014 14:30:42 GMT
Perhaps a constructive answer would help the original poster here.

Since your bottleneck is the lack of actual RAM, then I would recommend
using a threaded mpm like event, which will allow you to support far more
clients with less resources. With 2.4, you can simply load the appropriate
mpm with the LoadModule directive.

As for php support, I recommend using mod_proxy_fcgi to translate requests
to a php-fpm pool. See the recipes on

As a ballpark figure, you can probably get away with two three httpd
processes using 5-7 MB of RAM each, and dedicate the remainder of your free
resources to php-fpm.
