Actually, I moved the scripts

Actually, I moved the scripts from my shared hosting test environment to the product dedicated server and it runs more than 10 times quicker?

Could my shared hosting on Hostgator really be so slow. The scripts call Kelkoo and another shopping service and get the products back as XML which I convert to PHP object and create a new array which I send the the client as json_encoded?

I am using cURL, simpleXML and json_encoded. Apart from this I load up 3 plugins and use the call_user_func() method.

Are any of these resource intensive?

Or could it be that Hostgator shared hosting is just slow and rubbish?

I've never used

I've never used function_exists(), but that seems like it could be a resource hog. According to the docs, call_user_func() "Returns the function result, or FALSE on error" so it looks like you don't need to check that the function actually exists.

I think this is going to be

I think this is going to be the main issue:

$these_hooks = explode('|', $this->hooks[$where]);

I would store it in an array rather than a string where you have to explode several of them on every page request.
