Hi
I don't think that dedicated vs shared server is the issue. Both sets of code exist on the same server in different directories. I would expect any impairment in performance to be the same on both sets of code since they share the same environment. I don't think load is the issue either for the same reason, I would expect both sets of code to impaired the same and poor performance to be shared between them and that doe not seem to be the case.

I just finished reading http://www.zen-cart.com/forum/showthread.php?t=153143 DrByte post has been very helpful. He indicates that "If you're using such an old version of PHP, then your site is certainly not PCI-Compliant" and indicates some unhelpful behaviors within the new code when used with older PHP version. I think these are reasons enough to recommend upgrading to newer version. I expect the server environment upgrade will fix the performance issue.

Thank you for your posts and inquiries, they have been very helpful in dealing with this issue.
