Is ini_set("memory_limit", "512M"); too much?
<p>I am using 2 php libraries to serve files- <code>unzip</code>, and <a href="http://www.phpclasses.org/package/2495-PHP-Pack-and-unpack-files-packed-in-ZIP-archives.html" rel="nofollow"><code>dUnzip2</code></a></p>

<p>zip    zip.lib<br>
<a href="http://www.zend.com/codex.php?id=470&amp;single=1" rel="nofollow">http://www.zend.com/codex.php?id=470&amp;single=1</a></p>

<p>They work fine on files under 10MB , but with files over 10MB, I have to set the mem limit to 256. With files over 25MB, I set it to 512. It seems kind of high... Is it?</p>

<p>I'm on a dedicated server- 4 CPU's and 16GB RAM - but we also have a lot of traffic and downloading, so I'm kind of wondering here. </p>
