I recently installed APC via the Module Install under manage PHP Pecl.

After installing with no issues I call up my php info file on my webserver and note the following:

I also managed to locate acp.php and copy it to my home directory and call up it up on the browser. I'm using to cache wordpress and drupal.

So I have 2 questions:
1) In the actual php.ini file I don't find the above info in it. I assume APC has it's own .ini file, if so where exactly do I find that .ini file and is it better to change the parameters on there or must I rather put that info in the php.ini file?

2) APC is running but when I call up apc.php I see the following:

User Cache and System Entries are empty?

Wordpress doesn't complain about APC but it doesn't look like it is doing any caching?

Hello :)

You can add your custom APC values directly to the /usr/local/lib/php.ini file. Also, could you let us know which PHP handler you are using?

Thank you.

If Fcgi is so difficult to configure , why does easy apache does not do it automaticly?

I'm running under suPhp, but how can I install APC if I don't change to fcgi ?

FCGI is not difficult to enable, but rather it often requires fine tuning of it's configuration based on your individual server usage. suPHP doesn't work with OPCode caching.

Thank you.
