Our site is running on a custom PHP/MySQL platform on a cloud hosting server (rackspace). Recently, the site has been slow and creates HTTP error 500 (Internal Server Error) messages pretty often. I need some expert programmer to take a look at the scripts and mySQL queries to see any further optimization needed. In addition to fixing the issues that are causing the site to be slow you will also recommend further improvement to speed up the site.
Only experts need to bid.
