We are having long-term problems with indexer and cache settings.
Problem: If I edit&save product A, then indexer "processed" changes in backlog(1). FPC (not sure if its FPC but product page load in 3 seconds instead of regular 200ms) of every product is invalidated not just for product A. This cause huge load issues on our production Magento installation.
