Note there is no speed improvement between PHP 5.4 and 5.5
Unless you need a 5.5 feature, best to wait.
Of course you can manually install the open-sourced zend opcode cache into PHP 5.4 and get the speed improvement from that.

Obviously going the "there is/isn't performance gains" flamewar route alone is a conversation nobody would win. So I would through this out there: If you have the capability to move to PHP 5.5, because there aren't performance penalties, you should - if for no other reason than it'll help you stay ahead of the PHP EOL sythe.
