I have a friend who needs help to get his online store running smoothly. The online store is built using Xcart and has trouble with speed and various other problems. The friend says he needs help with "optimizing a MySQL server running in a Plesk environment". You can see the website in its current state at www.teawithgrace.com.
He needs to fix the problem within the next week.
