Piwik.php running really slow - how to optimize?

So I set up piwik to remove the URL footprint which appears in the javascript by following the tutorial below:

http://piwik.org/faq/how-to/faq_132/

Seems to work fine, but the problem is my website is showing up slow in my performance tests.

I tracked it down to the call it makes to piwik.php.

Does it really take 8 seconds to run that script. Is their anyway to speed this up.

-Both the website and the domain where I set up my Piwik Install are on the same shared server.
-I am using wordpress and the W3 Total Cache plugin but still slow.

Any ideas?

Hi there, Maybe there is a DNS problem and it takes this long for your server to reach your other server? Sorry don’t know

As soon as I get myself a faster server, I’ll test it again.

Thanks Matt for the update
