Just one question, it's posible to change the default administration page folder? Instead of html/xcache can i put it somewhere else? How i do it? Thanks in advance.

If you want to use it for more than that you will need to edit the config file and possibly your code. @Kenny,

Is that all I have to do to utilize the XCache PHP opcode caching? Or do I modify my files to use xcache_set/xcache_get? I was assuming those were only for var caching. Thanks for your help.

I'm curious to know if you're aware of XCache having any issues with Plesk? (Specifically 8.2 or 8.3) I have a dedicated server with Rackspace that's about to go live with a php-heavy site. Rackspace reports eacclerator is prone to segfaults with Plesk, and you note above that APC had some issues under load as well as segfaults. Any idea if XCache would be a better solution under Plesk? Any insight appreciated. Jason, first, thanks for your original post and all the work you've done to follow up on it!

According to the output you posted you do not have the Zend Optimizer installed.

I found it odd that it was not in the /etc/php.ini file, and I have scoured it. Maybe I don't need to worry about it. When I look closer, in my phpinfo, It does not show the Zend Optimizer, only the following: Zend Engine v2.2.0, Copyright (c) 1998-2007 Zend Technologies with XCache v1.2.2, Copyright (c) 2005-2007, by mOo I am pondering that I don't need to worry about then, as I had already gone through all the loaded *.ini files for PHP, and no reference to Zend could be found. But I could very well be wrong. Thanks Jason. I found it odd that it was not in the /etc/php.ini file, and I have scoured it. Maybe I don't need to worry about it.

Installing the Zend Optimizer may have relocated your php.ini file. You can find the exact location, along with the locations of any ancillary config files, near the top of your phpinfo(). @Possum,
