Website Speed Optimization

Website Speed Optimization We are currently running an OSC 6.15 website on a MYSQL Database with custom database additions. We receive anywhere from 200-350 shoppers online at any given time. The site is extremely slow pulling up product pages and any other links which are dynamic. We are looking for someone that can diagnose the problem as well as fix it. I believe it may be a programming error when querying the database rather than a server bandwidth bottleneck. We are hosted on our own dedicated server. Requirements: Evaluation of our website Detailed report of why our website is slow. A Report of what will done to fix this issue. Estimated time of delivery after evaluation. Speed Testing
