Very Slow Wordpress Site - Killing MYSQL server

Hi , my wordpress website has some performance issues from both frontend and backend. Slow from frontend. Slow from Backend - but does speedup when I change to default website theme ( i obviously dont want to do this ) I have upgraded to latest version of Wordpress but I need someone to debug the mysql calls and also any broken code. The coder needs to first show proof of Wordpress Experience , then : A. Backup anything before any changes ( code ) B. Get my approval from new Plugin C. Document all work. D. Increase speed of both front end backend and prove how it was done. Please DO NOT suggest a Cache Plugin - there is an underlying issue that I need resolved before I know a Cache plugin will work. Payment will not be made otherwise. Wordpress Version is : Version 3.3.2 Website is at : [login to view URL] ## Deliverables Wordpress Experts
