[How to] Cut down on memory usage

[pmfp]

I have a problem with include's and phrases. It has been recreated in the files test.php and includes/test_include.php.

The problem is that the code is executed and the template fetched, but the phrase is not being printed. The nature of the real script means that I cannot use another plugin to insert the code, so that is out of the question.
Any ideas on how to do this properly?

test.php:

PHP Code:

<?php

error_reporting(E_ALL & ~E_NOTICE);

define('THIS_SCRIPT', 'db_update');
$phrasegroups = array('test_phrases');

include('includes/test_include.php');

require_once('./global.php');

did_it();
?>

includes/test_include.php:

PHP Code:

<?php

function did_it() {
    $varvar = "set";
    
    eval('print_output("' . fetch_template('test_splitter') . '");');
}
?>

test_splitter template:

<tr>
<td width="310" valign="top" class="thead">
	<if condition="$varvar==set">$vbphrase[test_hello_world]</if>
</td>
<td valign="top" class="thead"></td>
</tr>

I just added about 10 of my larger plugins to files, and I have noticed a considerable lag on the forum. Page generation times have increased from .10 seconds to 2 seconds or more, and server load has gone up from about 1.00 to anywhere from 8 - 40. 40!!!!!

EDIT: Looks like it was just a really bad night for server load. My forum seems to be running at the normal load today.

Do you still believe that outsourcing hugh plugins to includes will speed up your forum?
I don't think so. It sounds like it should improve the performance, but in real scenarios, it doesn't matter.

At least, have a look in the official addons like the blog software. They put their code in the plugins and not in files they include. They did it with high traffic hooks like fetch_userinfo... Haven't they thought about performance or doesn't that matter...
