Within the last few days the osCommerce portion of my website has started to load pages very slowly, about 15 seconds to load. My site has two separate sections; one is all html and the other is osCommerce. The html portion of the site is fine. It is just the osCommerce pages that are slow. Also, today I had my host enable the PayPal Pro module for the site. But the slowness began 3 days ago. I requested the change to PayPal Pro on the same day it started to run slow. What could cause the all of a sudden slow loading pages? Could it be mysql?
