PHP takes a long time for uncached pages
<p>On my server, PHP will take a long time to execute a script (say, 5 seconds) if it hasn't been cached by APC yet. After it is, it executes very fast.</p>

<p>I'd provide more information, but I wouldn't know where to begin. Can you guess and point me in the right direction? I'll edit this question once I have more info.</p>
