I'm trying to speed up Magento 220.127.116.11. It's taking something like a minute or so on localhost MAMP 5, and page speeds on production are loading over 10 seconds. I've tried full page cache extensions, removing overridden templates, disabling all third party extensions, and truncating large database tables. The site ran moderately fast for about 5 years. The first sign of problems was on the production server when the cart page started taking over 10 seconds to load.
