Virtual Domains

[mike]

first off here's a snippet of one of my fastcgi pools:

                        <value name="pm">
                                <value name="style">static</value>
                                <value name="max_children">4</value>
                                <value name="apache_like">
                                        <value name="StartServers">4</value>
                                        <value name="MinSpareServers">2</value>
                                        <value name="MaxSpareServers">2</value>
                                </value>
                        </value>
                        <value name="request_execution_timeout">31s</value>
                        <value name="rlimit_files">1024</value>
                        <value name="rlimit_core">unlimited</value>
                        <value name="catch_workers_output">yes</value>
                        <value name="max_requests">250</value>
                        <value name="allowed_clients">127.0.0.1</value>

i set max_children and StartServers to the same, although I believe
anything inside of "apache_like" is ignored for now.

but yes, engines = how many instances of php (via php-fpm) are running
per fastcgi pool

for example, above, it is 4 engines

correct

yeah, right now apache stuff is not completed

yes, and maybe StartServers for good measure

haven't needed to change this

i usually set mine a little bit lower. i don't really have any
benchmarks or evidence either way. originally when i was having issues
a while back i thought perhaps it was leaking too much memory so i
made it more aggressive by restarting processes after less requests.
500 should be fine. 250 should be fine. any number is probably fine...
